Operation manual of FB-PLC【Hardware】 Chapter 1 FB-PLC Introduction The FB-PLC has two main unit models FBE and FBN, the FBE is the standard main unit, and the FBN is a high speed NC positioning main unit, the instruction sets of both units are fully compatible. With respect to their function, the I/O frequency of NC positioning pulse of FBE may reach 20KHz, the circuit structure is single end method, while the I/O frequency of NC positioning pulse of FBN may reach up to 512KHz. In order to reach this high speed I/O, its I/O circuit employs dual line differential method.

● This socket is for insertion of EPROM/FLASH ROM/EEPROM which storing the user's ladder program and may with the data of registers. The main unit is built-in SRAM with batterry backup to store the user's ladder program and data of registers, if the socket is empty, it still works no problem. For the considerations of mass production of machine copy or for long term maintenance, the user may copy the program and data of registers storing in SRAM to the EPROM/FLASH ROM/EEPROM via FP-07B handheld programmer (The main unit also can copy the program and data of registers into FLASH ROM directly). Insert the copy of EPROM/FLASH ROM/EEPROM into the spare socket, the main unit will overwrite the SRAM with the copy of EPROM/FLASH ROM/EEPROM （the existing program in the SRAM will be replaced by the program of EPROM/FLASH ROM/EEPROM）every power on, and the PLC will be in "RUN" mode automatically regardless its "RUN" or "STOP" mode before. ● The socket is a 32Pin DIP type. The packs which can be inserted into this socket are with 256K or 512K bits (Both are 28Pin DIP packing) or 1M bits（32Pin DIP packing）memory capacity.
(Of the memory type, please refer to
paragraph 2.1.3 of "Basic manual") 16 32 Pin /28 Pin memory pack insertion direction and pin indication sticker ○
● Since the 256K or 512K bits memory packs are 28Pin DIP packing, but the socket of the PLC is 32Pin, there will be 4 empty pins left. Please observe the instruction on this sticker on how to install the memory pack and where to plug it into the IC socket (i.e. there are 4 empty Pins on top of the socket). And whether it is a 32Pin or 28Pin memory pack, the directional notch should be on the same side as the sticker.
Caution 1. The selection of memory pack follows the description of paragraph 2.1.3 of Basic manual, insertion of invalid memory pack（such as 28C256）may result in scrambled PLC data or loss of program or data, and produce unexpected action of the PLC and may endanger the unit, the equipment, or human safety. 2. Even though the selection of memory pack is correct, if the insertion of the memory pack into the spare socket failed to observe the direction/pin indicated on the sticker, it may result in scrambled PLC data or loss of program or data, and produce unexpected action of PLC and may endanger the unit, the equipment, or human safety.

15 Pin D−sub (Female)
FB-DTBR can be used to lead out 3 com. ports signals from the 15Pin D-sub connector of the main unit, it may transfer the port2 signals (RS-485) to 3-pin terminal block, and transfer port1 (RS-232) to standard 9Pin D-sub connector. Besides, converts port0 (HCMOS) signal into RS-232 signal first, and then transfer it to another standard 9Pin D-sub connector. To remain compatible with the peripherals of FB series at the same time, the signals (except D+ and D−) of the 15Pin D-sub of the main unit are transfered to the 15 pin D-sub's of FB-DTBR transparently. Following is the illustration of FB-DTBR: FB-DTBR or FB-DTBR-E

Note 1 ：port0 signal is present on the lowest 15Pin D-sub connector of FB-DTBR by HCMOS signal, and also is present on the 9Pin D-sub above the 15Pin D-sub connector as an RS-232 signal via a signal conversion. Whenever the FP-07 or FB-485P0 is plugged into the 15Pin D-sub thus the HCMOS port 0 will be connected to, the FB-DTBR will disable the converter automatically and make the 9Pin D-sub RS-232 of port0 floating. The 9Pin D-sub RS-232 (port0) will be operational only after removing the connection to the HCMOS port. Note 2 ：In addition of being converted to RS-232 signal in a 9Pin D-sub female connector via FB-DTBR, the HCMOS signal of port0 may be converted to RS-232 signal of 9Pin/25Pin D-sub female connector by using FB-232P0-9F/FB-232P0-25F communication cable with signal converter, or may also be converted into RS-485 signal of 3-pin terminal block by using FB-485P0.
FB-DTBR-E can be used to lead out 3 com. ports signals from the 15Pin D-sub connector of the main unit, it may transfer the port2 signals (RS-485) to 3-pin terminal block, and transparently transfer the 15Pin D-sub signals (except D+ and D−) of the main unit to the 15Pin D-sub's of FB-DTBR-E. Besides, converts port0 (HCMOS) signal into RS-232 signal first, and then transfer it to the standard 9Pin D-sub connector above the 15Pin D-sub. There is also a 9Pin D-sub connector to connect to 10 Base-T Ethernet, it is the interface of FB-PLC to enter the Ethernet environment. Following is the illustration of FB-DTBR-E:

I/O Expansion and System Combination
2.1 I/O Expansion and I/O Number Calculations The internal status of X0〜X255 are corresponding to the on/off condition of the external inputs connected to the input interface circuit, and the internal status of Y0〜Y255 are corresponding to the on/off state of the external outputs connected to the output interface circuit. On the main unit there are labeled with X0 to X23 and Y0 to Y15 (depending on the model and the number of I/O points); these labels on the input terminal blocks indicate the correspondence of the terminal inputs and the PLC internal input status X0 to X23 (for FBE-40MX); the labels on the output terminal blocks indicate the correspondence of the terminal outputs and the PLC internal output status Y0 to Y15 (for FBE-40MX). However, for expansion units or modules, the corresponding I/O number of the hardware I/O points should be calculated according to the figure below.

The input number of any point on an expansion unit/module is the number of the point added with the total number of inputs preceding of it. The same is true for output number calculation. As illustrated in the figure above, the input number of the 11th input point in the third module is found by adding 11 to the sum of the input points in all of the preceding units as shown below:
X (23+16+11) = X50 Note： The I/O expansion of FB-PLC are limited to 256 points for both input and output. When the total number of I/O points exceeds this upper limit, the PLC will not run.
Refer to the description in “Advanced Function Section” for the correspondence of the analog input／analog output register (IR/OR) and their external analog input (AI)／analog output (AO) module.

Chapter 3 Installation Precautions Danger 1. While installing the FB-PLC or other equipment connected, turn off all power supplies otherwise, electrical shock, or damage to machines and equipment may occur. 2. Cover the protection board on the terminal block and supply power for testing after completion of all installation and wiring operation in order to avoid electrical shock. 3. Never peel off the dust proof film on the ventilation holes of the PLC before completion of installation and wiring. This is necessary in order to prevent dropping of iron chips from drilling and other wire scraps into the PLC and causing damage to the PLC internal circuitry. 4. Remember to peel off the above stated dust-proof film after confirming completion of installation and wiring to prevent poor heat dissipation of the PLC and prevent damage to the unit from excessive heat.
3.1 Installation Environment Caution 1. The working environment specification of the FB-PLC should never exceed the environmental specification listed in section 1.5 in this manual. Besides, never use in environment with fume, conductive dust, high temperature, corrosive gas, combustible gas, rain, saturated humidity, and vibration impact places. 2. Whether used in a system or as a stand alone unit, this product should be installed in an appropriate cabinet, the selection of the cabinet and installation should comply with local or national standard requirement.
3.2 Layout of Control Board and Mounting of the PLC Placing of the PLC
The mounting design of the FB-PLC is facing transversely in front(horizontal position) and placed from left (main unit) to right (expansion unit/module), it can be fixed by using DIN RAIL or mounting screws, the figure below is the typical mounting method:

Heat Dissipation Clearance
The FB-PLC uses natural air convection for heat dissipation, thus sufficient gap should be provided for heat dissipation.
A min. of 25mm gap should be provided above and below the unit. There should be a minimum of 50mm clearance above the face of the PLC.
the direction of heat dissipating
Mounting Method DIN RAIL (DIN EN50022) mounting method • This method is not applicable to applications with high vibration condition exceeding 0.5G. • Pull the two DIN RAIL removal tab hooks at the bottom of the PLC simultaneously while pushing the PLC from
top to bottom.
Direct mounting by screws M3~M4 screw fixing method. • Use M3~M4 screw holes to directly mount on control cabinet. • There are three types of fixing holes for various models of FB-PLC as follows:

3.3 Precautions in Construction and Wiring 1. Please follow local or national standard regulations to proceed with installation and wiring of the FB-PLC. 2. Please notice the current load of the I/O wiring and choose the appropriate wire size. 3. Use as short as possible wires, the I/O wiring should not exceed 100m in any circumstance (less than 10m for high speed inputs). 4. The input wiring should be away from output or power lines (a distance of 30~50mm), make perpendicular crossing if separation is not possible, never run both in parallel. 5. There are two kinds of terminal blocks with the pitch of 9.52mm and 7.62mm, the torque ranges of screw are shown below: M3.5

Power Supply Wiring and Power Calculations
There are AC and DC power inputs for FB-PLC power supply. The code on all main unit and expansion unit that is followed by a “D” tail code, indicates that the internal power supply needs a DC input power, otherwise it needs AC power.

Caution The main unit and expansion unit wiring for the power supply are as illustrated keeping the following in mind: 1.
Please follow the local or national standards for wiring regulations using single cut switch (cut off live ”L”) or double cut switch (cut off both “L” and “N”) to turn ON or OFF the AC input power.
2.
The live “L” should be connected to the L terminal on the unit, and the neutral “N” to N terminal on the unit. The wire diameter should be 1mm2 to 2mm2.
3.
The main unit and all G terminals of all expansion units/modules should connect to EG (Earth Ground) terminal of the main power system. The conductive wire diameter should be more than 2mm2, for more details you might refer to the drawing below.
4.
For all units equipped with AC power supply, there are two sets of separated DC24V output power, one of them is used for output circuit and expansion module (comes out of the extension connector), the other is for use in input circuit and external sensors (comes out from terminals at input side). For the output current capacity refer to section (4.3) about calculation of power capacity.
Warning The output power used by sensors should not be connected in parallel to other power sources, this will cause conflict between the two sets of power supply and shorten the life span of both of them or produce immediate damage, resulting in unpredictable error action of the PLC that may cause death hazard or loss in property and equipment.

Caution The main unit and expansion unit wiring for the power supply are as illustrated keeping the following in mind: 1. Please follow the local or national standards for wiring regulations using single cut switch (cut off ”24V＋”) or double cut switch (cut off both “24V＋” and “24V－”) to turn ON or OFF the DC input power. 2. The DC24V＋ should be connected to the ＋ terminal on the unit, and the DC24V－ to － terminal on the unit; the wire diameter should be 1mm2 to 2mm2. 3. The main unit and all G
terminals of all expansion units/modules should connect to EG (Earth Ground)
terminal of the main power system. The conductive wire diameter should more than 2mm2, for more details you might refer to the drawing below. 4. For all units equipped with DC power supply, there is a 24VDC output power for output circuit and expansion module (comes out of the extension connector), the power for input circuit and external sensors directly comes from the external DC power supply. For the output current capacity refer to section (4.3) about calculations of power capacity.

4.3 Calculations of Allowable Current Capacity of Main/Expansion Unit, and Current Consumption of Expansion Modules As stated above, the main unit and expansion unit are both provided with power supply; in addition to their own usage, there are extra capacity of power for input circuit and external sensors, and output circuit and expansion module. Followings are the ratings of current provided by the main unit/expansion unit and the max. current consumption of expansion modules.
Caution When the main unit/expansion unit is attached to the external sensors or expansion module, regardless of the connections, the DC24V power supply used by input circuit and external sensors, or the other DC24V power supply used by output circuit and expansion module, the max. total current consumption should not exceed the allowable current capacity listed in paragraph 4.3.1, otherwise the power supply may enter protective mode due to overload and lower its voltage rating and resulting in unexpected action of the PLC, and may cause human casualty or loss of equipment or property.

Because there is no power supply in the expansion module itself, therefore the circuit power supply regardless if input circuits, or output and control circuits are supplied externally. This includes, the power supply of input circuit supplied by 〝DC24V INPUT〞terminal on top of the expansion module, and the power supply of output and control circuit supplied directly from “expansion connector” at left of module. The current consumption listed in the table above is the max. consumable current (assuming that all input points and output points are “ON”, ( its input current consumption based on 7mA for every “ON” input, 9 mA for every “ON” output, and 1.2mA for every "ON" output of high density) of each expansion module.

The inputs other than DC5V differential input on FBN are DC24V input circuit. Regardless of being a main unit or expansion unit/module, there is medium speed and low speed response in DC24V input on main unit, and the DC24V input on the expansion units and expansion modules have low speed inputs.

Warning There is a DC24V power supply provided for external sensors in the PLC main unit or expansion unit, but with limited capacity. External power supply is required in case of insufficient power as illustrated at above. Pay special attention for the negative of the external power supply and should be connected to the negative of the DC24V provided by the PLC. But never connect the positive side of both (i.e. no parallel connection). Parallel connection will cause conflict of both power supply and burn the PLC power supply or both, resulting unpredictable PLC output and may lead to death of personnel and major loss of equipment and property.
5.3.2
Setting Procedure of SINK or SOURCE Input Type of DC24V Input circuit
Warning 1. The setting of the SINK or SOURCE input of the input circuit is done before delivery; the user should specify the model of SINK or SOURCE input. Tampering of settings is not allowed. 2. Professional personnel may change the SINK or SOURCE setting as per following procedure, but there must be consistence in order to avoid maintenance problem later. Pay special attention to the orientation of the conductive plate of the jumper while setting the pin. Plug into the SINK or SOURCE position vertically according to the indication symbol on the pin of the left side of JP1. If incorrectly placed in transverse direction, it will cause short circuit of DC24V power supply, resulting in overload of the internal power of the PLC causing no output or burning the external 24V power supply, or leading to unpredictable output of the PLC causing death of personnel and major loss of property.

Digital Output Circuit
The FBN main unit is built in 1 to 4 points (depends on the model) of DC5V Line Driver high speed differential output, the output frequency can reach up to 512KHz; the others of outputs are same with the FBE'S, they are single ended and come in three different interfaces: transistor, relay, and TRIAC. For the purpose of saving output terminals, the common point output structure is employed. There are two points share one common terminal or more output points share the common terminal (refer to section 6.3.1); the common terminals are isolated from each other. The transistor output must have SINK output or SOURCE output configurations setting. Due to polarity requirement and common output relation, these settings are done in factory before delivery, and marked in the SINK/SOURCE column (indicated by “ ” symbol) on the output nameplate. Since there is no SINK or SOURCE in relay and TRIAC outputs, the SINK/SOURCE column on the output nameplate is left blank. The following figures are for transistor SINK output and the relay output or TRIAC output with no SINK/SOURCE identification follows:

6.2 Structure and Connection of DC5V Line Driver High Speed Differential Output As stated above, the FBN main unit is built in 1 to 4 points (depends on the model) of DC5V Line Driver high speed differential output, the output frequency can reach up to 512K Hz; the others of outputs are single ended and may be one of the three interfaces: transistor, relay, and TRIAC. Following is the description of DC5V differential output, the singled ended outputs are same with the FBE main unit's and will be mentioned in paragraph 6.3. The 5V differential output can be connected to the driver with photocoupler input or Line Receiver, as illustrated in the figure below. For the purpose of increasing noise immunity and signal quality, please connect with twisted pair having shielding at outer layer, and then connect the shielding with the SG of PLC and FG of the driver.

6.3 Single End Digital Output All digital output circuits except the DC5V differential output of FBN main unit, regardless the transistor, relay or TRIAC output are in single end common point output structure and described as follows:
6.3.1
Structure and Connection of Single Ended Transistor Output
The transistor's output circuit of FB main unit or expansion unit/module (except the high density) has an additional interchangeable bi-poles double jumper of C (collector) pole and E (emitter) pole on the output circuit. The reason is that the common point connected to one pole (E or C but can not be mixed together or cause short circuit) while serving as common point output, became sink output if connected to E and not available for SOURCE output and vice versa for SOURCE output but not for sink output. Thus the jumper make collector and emitter interchange available, you may choose the common point as E for SINK or C for SOURCE output. For the transistor on same common point, the setting should be consistence (all common E or all common C). The figure below is an example of the setting for SINK and SOURCE respectively of 2 points common-point block and 4 points common-point block.
6-3
Jumper place at "SRCE" position Jumper place at "SINK" position
DC power DC power
(2 points of one common point output block setting SINK)
(4 points of one common point output block setting SOURCE)
Warning 1. The SINK or SOURCE configuration of transistor output of FB main unit and expansion unit/module are set in factory before delivery, the user should select the SINK or SOURCE output model depending on the application and should not modify the setting arbitrarily. 2. Qualified professional personnel may change the configuration setting of SINK or SOURCE according to procedure in section 6.3.3, please change the notation on the output nameplate simultaneously when modifying the setting in order to avoid confusion on latter maintenance. Though all common-point output blocks are separated from each other, different blocks can perform different output configuration settings, (the transistor outputs in the same block should be identical absolutely), avoid different setting if possible to prevent confusion, note the description if necessary to rouse the attention of maintenance personnel. 3. Pay special attention to the fact that the setting of transistor module in the same common-point output block should be consistent (All SINK or SOURCE) during setting, and label with symbol on the pin direction beside JP1 on the transistor module while inserting the pin, insert the conductive plate of the pin vertically into SINK or SOURCE position. Inconsistent settings in the same common-point block or wrong insertion of the pin in cross direction, or inconsistent settings in the same block will result in short circuit of output points and constant conduction which causes error action, and may cause fatality or major property loss.
6-4
6.3.2
Increasing the Response Speed of Transistor Output Circuit
Though the circuit structures are identical in the transistor output of FB main unit, the speeds are divided into low and medium, and the transistor outputs of all expansion are in low speed. There are different restrictions in the load current of low and medium speed transistor output. Medium speed transistor output (frequency up to 20KHz) The Y0~Y1 of FBE-20MCT, Y0~Y3 of FBE-28MCT, Y0~Y7 of FBE-40MCT are medium speed transistor outputs. The application is mainly used in pulse output for positioning control driven by stepping or servo motor, in order to gain faster frequency response, there are upper and lower limit in load current, the 0.1A load current has optimal effect, because the input resistance of the general driver is quite high and tend to draw small load current, this will cause the extension of ON→OFF time. Therefore, please add in the virtual load illustrated in the figure shown below to make the load current equal to 0.1A.
PLC transistor output Load Pseudo load resistance R
0.1A current
Low speed transistor output (frequency lower than 300Hz) The transistor outputs of expansion unit/module other than medium transistor outputs of FB main unit are in low speed, the maximum output current is 0.5A, the response time under rated current is <0.2ms, but the response time from ON→OFF is longer if it is under light load. This will be improved by increasing the load current by using the virtual load illustrated in the above figure. Though the output current of every point of the transistor outputs may go up to 0.5A, do not exceed a maximum current of 0.4A (while 2 outputs sharing a common point) or 0.3A (while 4 outputs sharing a common point) at each point while multiple points are ON at the same time to avoid increase in temperature and possible damage to the unit.
6.3.3
Setting Procedure of Single End SINK or SOURCE Transistor Output
(1)
All setting changes should be executed under power off condition to the PLC.
(2)
Open middle small cover plate on the upper cover, remove the lithium battery from the battery holder on the upper cover, unscrew the screws surrounding the upper cover and remove the cover, the transistors output will be found.

6.3.4
Transistor Output Circuit of High Density Module
The high density expansion module only provides the low speed SINK type transistor outputs, and the loading current of each output is limitted under 0.1A. For easy wiring, the I/O cable HD30-22AWG-200 is the better choice to meet the requirement. The output circuit and wiring diagram are shown below:

Protection and Noise Suppression of Transistor Output Circuit
The transistor outputs of all FB-PLC are equipped with an anti-potential protection diode. It is sufficient in the applications involving small power induction loads with low ON/OFF frequency; but in the high power or high ON/OFF frequency applications please provide suppressing circuits as shown below in order to reduce noise interference, and prevent over-voltage or over-heat damage to the transistor output circuit.

Action frequency(10,000 times)
Due to non-polarity in the contact of relay it can be used to drive the load in AC or DC power supply. Every relay provides a max. 2A current, the max. current of all common points is 4A. The mechanical action life may go up to 2 millions times, but the life of the contact is shorter and varies depending on the working voltage, kind of load (power factor cosφ) and the extent of the contact current. Relevant correlations are illustrated in the figure below. For example, the life of the contact at pure resistance load (cosφ=1.0) under 120VAC, 2A current is 250 thousands times, and the life span is reduced dramatically to 50 thousands times at cosφ= 0.2 at high induction resistance or capacitor resistance load of less than 1A (AC200V) or 80 thousands times (AC120V).

Protection and Noise Suppression of Relay Contact
For an inductive load, regardless if it is AC or DC power, suppression components should be connected in shunt at both ends of the load, in order to protect the relay contact and reduce the noise interference. In case of DC power, the method is as per section 6.3.5, “Protection and Noise Suppression of Transistor Output.” Similarly, follows the method shown below with AC power.

6.3.8
Structure and Connection of TRIAC Output Circuit
AC power
AC power
The TRIAC output can be used in AC load only, and due to the TRIAC need to maintain its conductivity, the load current should be larger than the holding current (25mA). Thus, when the load current is smaller than 25mA, virtual load should be connected in parallel with the load current to make the load current larger than the holding current of the TRIAC. Besides, there is a 1mA (AC100V) or 2mA (AC200V) leakage current even if the output circuit of the TRIAC is in the OFF state. Beware of the trace current activating the load, use a virtual resistance connected in parallel with the load to eliminate the affect of the leakage. The rated current for every TRIAC output point is 0.3A, but never exceed 0.2A in case of multiple points conducted simultaneously in the same common block in order to avoid internal temperature rise and affecting the life span. Refer to section 6.1 for outputs requiring interlock.

Test Run, Monitor and Maintenance Warning
Turn off the power to the PLC before connecting any terminal on the PLC, or before plugging in or removing components (such as extension cable, program memory etc) during maintenance. Otherwise, you may cause electrical shock, short circuit, or risk damaging the PLC, or causing error action on the PLC.
7.1 Inspection Prior to First Time Power Up after Completion of Installation 1. Clean all wire chips, screws and debris before power on.
Peel off the dust proof film cover on the ventilation grid
on the side of the PLC. 2. Confirm the specifications of the input power and the installed PLC in case of AC power supply, remember to connect the live (L) to “L” terminal of the PLC, neutral (N) to “N” terminal of the PLC. Electrical shock or serious damage may be caused to the PLC or other equipment in case of wrong power connections such as DC feed power or wrong AC supply lines. 3. Confirm the consistency between the load power and installed PLC output component, damage or error action will result if you apply AC power to the transistor output of the PLC, or DC power to TRIAC output. 4. Confirm the consistency between the SINK/SOURCE polarity of DC24V input or transistor output and your wiring, error matching may cause failure of PLC input and damage to output circuit.
7.2 Operational Test and Monitoring FB-PLC provide the functional ability to disable all inputs or outputs one by one or as a whole, i.e. though the PLC perform actual program scanning operation and I/O update action, it will not update the disabled input status according to actual external condition, and send no actual output result of execution to disabled outputs, instead it sets the status of the input or output point as forced by the user, in order to perform simulation of action. The user uses the disable function match with monitor function to simulate the input or output via FP-07 or PROLADDER, and observes the consequence of its algorithm, and enable all inputs and outputs to resume to normal operation for correct operation. Please refer to paragraph 2.2 “Fundamental Function Section” for the description of RUN/STOP PLC, disable/enable I/O contact and monitor I/O status or operation of the contents of the registers.
Warning Disable function is to detach the normal program control of the input or output point of PLC and allow the user (tester) to force the setting of the input or output point by switching them to ON or OFF freely. During normal operation of the PLC, care should be taken while forcing input or output points concerning safety (such as upper and lower limit detection input or emergency stop output). This is necessary in order to avoid damage to machinery or equipment or human injury.

7.3 LED Indicator on PLC Panel and Determination of its Abnormality system error input "ON" indicaotor
low battery indicator transmission indicator "485"
output "ON" indicator power indicator RUN indicator
Power indicator〝POW〞 1.
After powering up the PLC, the “POW” LED located at lower left of the PLC will come on if the power mains match with the wiring, this indicates normal supply of power. If the LED fails to come on, try to temporarily remove the wiring of DC24V output power for sensors. If the LED lights up, it indicates that the power load of DC24V sensors is too large, and have caused the PLC feed power circuitry to enter the low voltage protection mode. In this case, an external DC24V power supply should be used. (The LED doesn’t come on and “hissing” sound can be heard if the PLC enters the low voltage output protection mode. This can also determine whether the DC24V output is overload or shorted)
2.
If the above method failed to make the “POW” LED come on and you are sure that there is correct power input on L, N (AC) PLC power input terminals or +, − (DC), then the power supply my be malfunctioning.
Running indicator〝RUN〞 This LED remains ON while the PLC is in the RUN mode. The PLC stays in the STOP mode while ex-factory. If you intend to make the PLC enter the RUN mode or return to the STOP mode, you must execute this command via the FP-07 hand-held programmer or the PROLADDER software from the PC. Once the PLC is set to RUN or STOP, the status will be maintained it will also resume after power interruption. The only exception is when the ROM PACK is used, the PLC will enter RUN status automatically whenever power to the PLC is resumed regardless it was in RUN or STOP state before power interruption. The PLC will enter STOP state automatically if error happened (such as WDT timer action, program error) during normal operation of the PLC, and the “ERR” indicator light comes on if this error is attributed to a secondary fault (such as occurrence of WDT or temporary interference). The RUN status will be resumed by recycling power. In case of a major error, the cause of error should be resolved first and then the PROLADDER Software should be used to run the PLC. If you fail to make the PLC enter the RUN mode, please send it to the nearest dealer for repair.

Error indicator〝ERR〞 1. The “ERR” LED comes on together with the “POW” LED at the instant of power up, but goes off after 0.5 second. If the “ERR” LED light stays on constantly, it indicates PLC failure. If it is blinking, it indicates that there comes the error in the main unit (such as watchdog time-out error, program error or system error.) 2. If the “ERR” LED lights on constantly, please turn off the power and then switch it on again. If it remains on then it indicates CPU hardware failure and send for repair. 3. The PLC is unable to communicate or perform any action under constantly red error light on condition; if it is blinking, connecting with FP-07 handheld programmer or PROLADDER software executing in PC to acquire error code in order to determine the error condition. The other way to identify the errors described below: a. The "ERR" LED is flickering with 0.25Hz (ON 2 seconds and OFF 2 seconds alternately), it means watchdog time-out error. Please turn off the power and then switch it on again, or check the ladder program whether there is endless loop or the scan time of PLC exceeding the setting of watchdog time-out timer. b. The "ERR" LED is flickering with 1Hz (ON 0.5 seconds and OFF 0.5 seconds alternately), it means ladder checksum error. Please turn off the power and then switch it on again, or check whether the battery low or the unexpected error while programming. c. The "ERR" LED is flickering with 10Hz (ON 0.05 seconds and OFF 0.05 seconds alternately), it means system error. Please turn off the power and then switch it on again, or check the ladder program whether there is illegal RTS or RTI instruction destroying the system stack.
Low battery indicator〝BTL〞 Power on the PLC, the “BTL” LED will not come on if the lithium battery of the PLC main unit is normal, but the “BTL” will come on if the battery is exhausted and lead to insufficient voltage, and the battery voltage is low and activating internal relay M1928 of the PLC. The battery can be used for one more month after the “BTL” comes on, the program of the PLC or the data in the battery backup RAM may disappear or become scrambled if this condition exceeds one month and after power has been interrupted. Thus, the battery should be replaced as soon as possible. But the effect of this indicator is minimal in actual applications since the PLC is usually installed in the control box, and the lifetime of the battery is unpredictable with large time variations and one may not be able to notice the “BTL” LED when it comes on. So, it is a bad practice to replace the battery by relying on the “BTL” indicator. (Refer to section 7.4 for correct replacement procedure).
RS-485 transmission indicator〝485〞 (MC model only) The RS-485 is the third communication port of the MC main unit, there is no display of “485” indicator during receiving, but display (comes on) only when the PLC performs 485 data transmission. Because the RS-485 can have multi-drop connections, but only one unit can perform transmission at a time, and all others perform receiving, i.e. only “485” light of one PLC unit will come on in any instant. Thus operation of each station can be easily monitored via this indicator. The light intensity is constant (current), but the time of light on is consistent with transmission data. Thus, visually, the light duration is higher if the transmitted data is large and the transmission speed (bps) is lower, and the light duration is lower if the data is less and in high speed. If the light does not come on at all, confirm whether the program is accessing this PLC station. If it is accessing the station but still doesn’t come on, please check the hardware wiring if it is inserted firmly, correct polarity of twisted pairs (D+ to D+, D- to D-), or check wire terminators.
Input indicator〝Xn〞 When the external input Xn is ON, the corresponding LED Xn indicator comes on, gone in contrast. Check the wiring terminal for good contact or measure the voltage at Xn and common point “C” if the indicator doesn’t correspond to the real input condition. It should be consistent with the input ON/OFF conditions and should present about 0V/22V voltage variation when checked with a voltmeter. If the indicator doesn’t correspond to the external input condition, it indicates faulty input circuit to the PLC or LED failure and you may use the monitoring mode of the PROLADDER to monitor whether the status of this input point is consistent with the external input in order to determine the cause of defect.
7-3
Output indicator〝Yn〞 When the status of output Yn is ON, the corresponding output indicator Yn will come on and make the external load ON. Check the wiring terminal for good contact if the indicator doesn’t correspond to the external output condition or the ON/OFF indicator. If the contact is correct and good, then there is failure in the output component of the PLC. The major causes of failure in the output components of the PLC are: (1) overload or short circuit causing output component of the PLC to become constantly opened or closed, (2) no overload, but the inrush current of a capacitive load caused the contact of the relay to become permanently ON, or has destroyed the TRIAC. (3) no overload, but there is a conductive load without adding an appropriate snubber to it.
7.4 Maintenance The suggested maintenance for the user during operation of the FB-PLC is only replacement of the Lithium battery. For other defects, please replace the complete board, and send the defected part to your local dealer for repair.
Time to replace battery Caution The program and the data in the PLC memory may be lost if the battery is not replaced within one month after the low battery indicator “BTL” comes on.
Please follow the following methods to replace the battery, we
recommended the second method below.
The life span of the lithium battery varies and depends on the surrounding environment (mainly the ambient temperature), energy consumption, type of internal memory used inside the PLC, and whether an RTC is installed. The variation of battery life is between 5 and 10 years or more. There are two methods for timing battery replacement: (1) regularly replace in three years’ interval, (2) continuously check the status of M1928 relay which captures the battery low indication in the program (the status will be ON when the battery is low). When M1928 is ON, alert the user to replace the battery by sounding an output alarm, or send a message from the PLC to a computer or a human-machine interface. This makes use of the battery full life and avoids potential problems in frequent battery replacements that may cause data and program loss from memory.
Replacement procedure of the battery 1. Remove the small cover plate at the center of PLC. 2. Take out the old battery from battery holder and remove it from socket. 3. Place in the new battery and insert back into its holder. Complete steps 1 & 2 within one minute if the operation is performed under power off condition to the PLC power Supply. Otherwise do the same under power to the PLC. 4. Replace the small cover.
Warning Never re-charge, disassemble, heat, or discard the used battery into fire. It may cause explosion, fire, or other hazard.
The internal substance of the battery may cause
environmental pollution, do not discard arbitrarily, please dispose according to local or national regulations for waste battery disposal.
