ABB Instrumentation AC-19
The MOD 30ML is a microprocessor based multiloop controller comprising built-in and modular I/O, removable terminations, signal conditioning, power supply and operator interface in a single instrument package. In addition to its two built-in isolated universal analog inputs, two current outputs and communication port, up to eleven single point local process I/O modules and one communications module can be installed in one controller. A flexible configuration allows these combinations to meet specific control needs.
FUNCTIONALITY The MOD 30ML provides continuous control functions such as PID, feedforward, set-point and output tracking, external feedback, set-point and output limiting, in addition to logic and I/O functions. The number of loops run in a single MOD 30ML is defined by the user and is based on desired execution time and I/O requirements. Up to six single loops (four cascade) may be implemented through front face configuration.
Runtime operation is normally supported through the instruments operator front face but may be supported through PC-30 Series Software (specification 23-10-03) or Intellution’s FIX (specification SS FIX/DMACS) running in an IBM PC/AT compatible computer, or an industrial workstation, or through third-party software or terminals using Modbus protocol. Local display and operations can be provided using the 2021W Local Control Panel over the ICN.
MOD 30ML also provides Sequence Blocks based on a drum programmer design with up to 100 inputs, 80 steps and 30 outputs per block; blocks can be cascaded for larger sequences. The Sequence Block allows forward and backward stepping, unlimited branching and outputs configurable for any data type supported by MOD 30ML (discrete, floating point, integer, time, date, ASCII or HEX).
COMMUNICATIONS Two serial communications channels on each MOD 30ML instrument allow up to two independent networks to function simultaneously. The first channel of serial communications is provided with the base instrument and is jumper selectable to be either Instrument Communications Network (ICN), RS-232 Modbus or RS485 Modbus. The second communications channel is available through the use of an optional serial communications module inserted into one of the eleven module positions. Communications modules are available for ICN, RS-232 Modbus or RS-485 Modbus. The RS-485 Modbus module is available in 2-wire or 4-wire forms. The 4-wire form can be selected to provide the power, pull-up and pull-down resistors required to stabilize a bus when MOD 30ML is used as a master.
BASE PLATFORM The base unit is available in two physical formats to suit different types of installation. Standard format includes a fifty position, two piece terminal block assembly for direct connection of field wiring at the back of the instrument. The second format provides a MOD 30 cable connection assembly permitting MOD 30ML to interface directly with existing MOD 30 termination equipment.
Peer-to-peer communications to other MOD 30ML, MODCELL Multiloop, MOD 30 Instruments, PC-30 Series Software and PC-30 Industrial Workstations is accomplished through connections to the ICN allowing seamless integration into both existing and new control strategies.
The instrument is available in 24Vdc and 85-250Vac. The MOD 30 instrument style is available in 24 volt DC power only. Both formats include a high speed Motorola 68302 CPU, and, associated firmware to support I/O, communications and control functions. Each MOD 30ML has 64K of non-volatile RAM which contains the user database and all current process and operating parameters. The optional Portable Memory Module provides 64K of redundant, removable non-volatile RAM which backs up the configured database and, if left on the instrument during operation, collects current process data.
Communications to MODCELL 2050 single loop controllers, various host systems and commercial terminal devices can be accomplished using standard Modbus RTU protocol. Both ICN communications and Modbus communications (Master and/or Slave) can be used on an instrument simultaneously.
CONFIGURATION AND OPERATION Configuration of the instrument is accomplished via one of two methods. For most applications including single loop PID, single station cascade and feedforward, canned strategies and faceplates are easily implemented through the instruments front face. For more complex applications, beyond those offered as canned faceplates, configuration is accomplished through the icon-based Application Builder Software which is used to create, edit, save, download and document the MOD 30ML data base in a graphic environment (see specification 23-10-06). Downloading instrument configurations can be done via ICN, or via Modbus over RS-232 or a 4-wire RS-485 network.

PROCESS I/O
signal conversion. A single module supports all thermocouple types with upscale burnout detection. Cold junction compensation is also provided. One current input module type supplies isolated loop power for 2-wire transmitters. Other input types include volt, millivolt, 2- and 3-wire RTD with upscale burnout detection and current input without loop power. The analog output module supplies 4-20mA or 020mA. All analog I/O modules are individually, optically isolated to 250Vrms continuous.
MOD 30ML provides two isolated universal analog inputs and two current outputs as standard. Each analog input can receive direct connection of either milliamp (2-wire or non 2wire), millivolt, volt, RTD thermocouple or resistance. Inputs have full galvanic isolation. Both analog outputs can be user set between span limits of 0 and 20 milliamps.
Digital I/O Digital I/O is selected by the user through use of digital I/O modules. Options include both isolated and non-isolated modules. Solid state relay versions offer high isolation voltage capability. Non-isolated modules are compatible with TTL logic levels and provide the ability to interface between similar modules without the need for an external power supply. The Mechanical Relay output module supports Form A, Form B and Form C relays.
In addition to the above base analog I/O offering, MOD 30ML can receive up to eleven process I/O and communication modules. Individual modules can be purchased separately based on application need. Plug in modules include various types of analog input, analog output, digital input, digital output, Instrument Communication Network (ICN) and MODBUS serial communications. Signal conditioning, failsafe and power fail/recovery parameters may reside in each individual module.
Extended Digital I/O Extended input and output modules expand the MOD 30ML digital I/O capability to 100 discrete points. The I/O modules communicate to MOD 30ML over the CS-31 Extended I/O Network using a 2020N communications module. The communications module does not need to use a communications position thereby leaving those two positions on the MOD 30ML open for communications modules. Refer to specification SS Remote-I/O for details.
Analog I/O Modules Analog input modules provide high-resolution signal conditioning. Process signals including RTD and thermocouple are connected directly to the MOD 30ML termination without requiring transmitters or transducers for

APPLICATION EXAMPLES Pipeline Booster Station Pipeline booster control requirements include the ability for the station to operate within safety limits. In this example MOD 30ML is used to cycle the booster pumps, provide suction and discharge pressure control with feedback, low signal selector and if needed, ramp function generator for remote start-up. The strategy is designed to operate within the safety limits.
3-Element Drum Level Control In this example MOD 30ML provides the steam flow linearization, feedwater flow computation (sum), drum level control, feedwater flow cascade control and auto/manual mode transfer. Both the control loops can have dedicated loop displays or they may be combined for a single station cascade look.

Select base instrument including instrument power supply and termination style required (Part 1). If required, select I/O Modules (Part 2). Eleven total slots per base instrument. Number of modules per base instrument depends on: - number of available channels after communications module(s) installed - slot requirements of each module, e.g. 3-wire RTD requires 2 slots (caution: 2012AZ active analog input and 2003AZ current output modules require the adjacent slot to be unused) If a second serial communications port is required, select the appropriate Communications Module (Part 3). One additional serial communications network beyond the channel on the base instrument (ICN, Modbus) may be installed on one base instrument.
