APPLICATIONS • Life Cycle Testing • Interlock system monitoring • General Alarm and Event logging • Security Alarm system monitoring Sequential Events Recording An event is any change of state in a process which is important enough to warrant some form of permanent recording of that change. This may be going into or out of alarm state. The purpose of the Sequential Events Recorder is to log these events onto a printer with date and time stamp and a useful message for engineers and maintenance staff to analyse what happened. This makes the SER an invaluable tool for plant maintenance or process diagnostics.
Input Types Omnilog caters for two input types of input. Firstly potential free field contacts. (relays or switches) using input card type C6203. Sense selection i.e. N.O. alarm or N.C. Alarm are set via DIP switch on the card. Option 2 is the Omni16 Input card intended for use with OMNI16 annunciators. This is a complimentary function for alarm annunciation with the events logged as they occur by the Omnilog.

Input Resolution Resolution, or input scan rate is the speed at which Omnilog is able to discriminate between inputs changing state. This resolution depends on the number of cards fitted to the Omnilog. Omnilog automatically senses the number of cards that are plugged in and adjusts the scan rate to suit. With the maximum 4 Input cards fitted (128 Inputs) the scan rate is 4 milliseconds this scan rate improves with less cards fitted to 1millisecond with 1 card (32 Inputs). So inputs can be differentiated down to 1 millisecond. An event buffer of 250 events ensures that events are captured even when rapid so that even when they overtake the print speed a correct chronological sequence of events list is maintained and no events are lost. Field inputs are continuously self tested and any circuit faults will appear as an event on the printer along with the fault output at the rear of the unit being triggered. Inputs are also digitally filtered for to prevent spurious false triggering of events due to contact bounce or induced electrical transients on cabling.
Integral Plain Paper Printer
C6202 Input Card for Omnilog – Omni16 Inputs
A built-in impact printer on the front panel prints onto plain paper in a 5x7 dot matrix format. The disposable ribbon cartridge is easily replaced at the end of its 10000 line lifespan. The printer uses a standard paper roll, which is accessed by hinging the front panel door down. 24 Characters per line are printed, at a speed of 0,7 lines per second. All printer message programming is done via a PC message editor and EPROM programmer.

Omnilog Model C1450 128 Point Sequential Events Recorder
The only maintenance required is paper and ribbon replacement.
LED Diagnostic Aids and Fault Output OMNILOG can detect certain faults in its operating system. If any of these occur, then a dedicated fault output on the CPU card, with terminals at the rear, will be activated. The fault output takes the form of an open collector transistor capable of switching 100mA at 24Vdc. It is switched on during normal operation and turns off when a fault is detected in the system. When this occurs the front panel power LED flashes continuously to draw attention to the problem. In addition the ‘paper out’ LED turns on when the paper roll is finished. An added diagnostic aid, is an LED which monitors the internal power supply.
Front Panel Diagnostic Aids
User-Definable Message Format: Where more comprehensive descriptions are required, then a separate plug-in User-Definable Message EPROM can be programmed with any alpha-numeric messages, using a PC and Omnilog message editor software and an EPROM programmer. Messages programming services can be supplied by Omniflex. A total of 16,000 characters is available in the Message EPROM, giving an average of 125 characters per input point, if all 128 points are used. However, each message may contain a maximum of 255 characters if less inputs are being used. User definable messages are in addition to the Standard Messages. Two User Messages may be defined for each point, one for alarm and one for normal. The messages are then burned into the EPROM by an EPROM programmer which is connected to the PC. This EPROM is now ready for insertion into the spare socket available in the OMNILOG, and all events logged will now be printed with the user-defined messages. These can be changed at any time, as the EPROM can be reprogrammed.
Two Message per Point
Any Alpha Numeric Message for each Input Two printout formats of logged events messages are available. Standard Message (Default option) and User definable Message (Optional). Standard Message format is the basic in-built default settings for Omnilog Messaging prior to the user programming own user defined messages into a message EPROM. Standard Message Format: When an event is logged in Standard Message Format, then the Time, followed by a 3 digit Input number(001 to 128), followed by the letter ‘A’ or ‘N’ (representing Alarm or Normal respectively) is printed on a single line.. 13:47:29:724 13:47:25:232 13:47:19:988 13:47:16:504

Power-up self-test Printout On power up, OMNILOG performs a comprehensive selftest. IN addition, the time of the last power failure, plus the immediate power-up time are recorded. This is followed by bit-by-bit RAM test and finally a full “SUMMARY” printout, as shown below.

The built-in front-panel printer may be optionally deselected if only an external printer is required.
•
The fault output can be programmed to operate every time an input changes to the “alarm” state. It is reset by depressing the “Time” button on the front panel. This converts OMNILOG to a printing annunciator.
•
A 24-character I.D. Message can be programme to print out during the “Summary”. This is useful for identifying which OMNILOG the printout belongs to. Useful when many Omnilogs are in operation in the Plant.
Communications I/O An RS232 serial port is available at the rear of the OMNILOG, for connection to a remote VDU or printer. Standard ASCII is transmitted at 1200 baud, with the format being 1 start bit, 8 data bits and 1 stop bit, with not parity. 80-column VDU’s and printers will display messages in 80-column format, unless they have been programmed into the User EPROM with carriage returns to effect a 24 column display. This communications I/O is exceptionally useful where central data display is required in a large plant.
