DTA 201 and DTA 202 Secondary Backplanes

Up to three secondary backplanes may be used in a Compact 984 system. The system maximum is four backplanes. Secondary (or extension) backplanes may be mounted to the right of the primary (DTA 200) backplane on a common DIN rail or beneath the DTA 200 on another DIN rail. The secondary backplanes contain either two (the DTA 202) or five (the DTA 201) 30-receptacle connectors for I/O modules. Secondary backplanes contain a bus extension ribbon cable with a 30-receptacle connector. This allows backplanes to interlock along a common DIN rail via the ground extension strap.

If a DTA 202 backplane is used it must be the last backplane in the system, and only one may be used. This is because the DTA 202 does not having bus extension connector on the right side.*

Controller Option Modules for 984 Slot Mount Series

Hot-Stand by Processor

A Hot-Standby System has been designed for applications that demand fault-tolerant, high-availability performance. Two identically configured 984-660 controllers communicate with each other through two S91 l-800 Modules, one in each controller housing. Each controller has the loadable HSBY function block installed.

One controller is designated as the primary controller - it reads input data from RIO drops, executes the stored user programs from memory, and sends appropriate output commands to the RIO drops. The primary controller also updates the standby controller with current system status information at each scan.

The standby controller processes only status information, not control functions; it does not interfere with primary control operations. It will assume primary system control in no more than 48 ms if the primary controller fails.

The Hot-Standby System does not support local l/O applications. Therefore, never plan to control critical l/O applications locally. Use the S908 RIOP with the 984-680 controller.

Power Supply

A P930 Power Supply Module provides enough DC power to support a 994X Controller with two option modules in a four card controller chassis. The P930 must be placed in the left-most slot.

At +5V, a P930 provides 15A maximum steady state and 3A minimum load current. It can handle input spikes of 220-400V for up to 20 ms and 1OOOV for 500~s.

The figure below shows the P930-000 Module with the front access cover removed. This module has an ON/OFF AC Power Switch (toggle) and five connectors which allow selection of either 115V or 220V input with use of a jumper. The P930-001 has three input terminals and one switch: the switch is the ON/OFF switch.

Central Processing Unit

The C916-120 high speed CPU Module processes 1000 words of typical user logic in 0.75 ms (200 ns/instruction). Its design uses bit slice microprocessors configured in a 16 bit architecture.

For time sensitive applications, a Time of Day clock rated as near-chronometer quality (accurate to +/-5 seconds per month) is provided. The clock has a replaceable five year battery located behind the top of the faceplate of the S929 MOP Module.

l NOTE The C916-120 CPU Module used in a 964X Controller is not interchangeable with the C916-100 used with the 964A Controller.

Multi-Option Processor

The 984X Controller uses an S929-001 Multi-Option Processor (MOP) that combines memory functions, communications processing, and I/O processing in one module.

The MOP supports one local drop of 800 Series I/O and an additional six drops of remote I/O using the S908 communications protocol; it will not support the S901 Remote I/O protocol.

The Remote l/O Port (coaxial), two 25pin MODBUS Ports, and one 37-pin Local l/O Port are located on the bottom of the MOP module. Although it does not have an ASCII/DAP Port, the P985 Data Access Panel can be used through either of the MODBUS Ports; Simple ASCII devices are not supported by the 984X.

Power Supplies

A P930 Power Supply Module provides enough DC power to support a 984A or 9848 Controller in a four or seven card chassis containing an S978 MODBUS Modem Module and one other option module. At +5V, a P930 provides 15A maximum steady state and 3A minimum load current.

A P933 Power Supply Module provides enough power to support a 984A or 9848 Controller in a seven card chassis with three option modules. At +5V, a P933 provides 25A maximum steady state and 6A minimum load current.

Both power supplies can operate on either 115V or 220V input power and within a frequency range of 46 to 63 Hz. Both the P930 and P933 must occupy the left-most slot of the controller chassis.

Controller Chassis for 984 A, B, and X

The 984A and 9848 Controllers are housed in either a 4 card or 7 card chassis; the 984X is housed in the same 4 card chassis. The left-most slot must be occupied by the applicable Power Supply Module, thereby leaving either four or seven slots available for other controller or option modules. The first slot after the power supply is referred to as slot 1.

Each chassis has option slots which have removable access plates on the bottom of some of the chassis slots. This allows access to module communication ports which are located on the bottom of some modules. The 4 card chassis has access plates on slots 1, 2, and 3 and the 7 card chassis has access plates on slots 1, 2, 5, 6, and 7.

Controller Option Modules For 984 A, B, and X

Hot-Standby Processor

A Hot-Standby System has been designed for applications that demand fault-tolerant, high-availability performance. Two identically configured 984 controllers communicate with each other through two S91 l-000 Modules, one in each chassis. Each 984 has the HSBY function block installed in ladder logic.

One 984 is designated as the primary controller - it reads input data from RIO drops, executes the stored user programs from memory, and sends appropriate output commands to the RIO drops. The primary controller also updates the standby controller with current system status information at each scan.

The standby controller processes only status information, not control functions: it does not interfere with primary control operations. It will assume primary system control in no more than 48 ms if the primary controller fails.

For more information see GM-S91 l-002, 984 Hot Standby System Programming, and GM-S91 l-001, 984 Hot Standby System Installation and Maintenance Manuals.

l Caution The Hot-Standby System does not support local I/O applications. Therefore, never plan to control critlcal I/O applications locally. Use the S908-011 or S908-021 RIOP with the 984A and B Controllers, and the S929 MOP Module for the 984X Controller.

MODBUS II Communications Processor

The S975 enables a 984 controller to send and receive messages over a MODBUS II Local Area Network. Each 984 on the network must have an S975.

The processor is not programmed directly. All communications are triggered by loadable function blocks in user logic or by a query from another controller. Each 984 on a MODBUS II network can be a master device and initiate communications. When communications are initiated by a function block, the 984 acts as a MODBUS master. When communications are initiated by another controller (by function blocks in user logic), the 984 acts as a MODBUS slave.

There are two types of function blocks available, MBUS and PEER. The MBUS block allows a controller to read and write discrete and register data between two controllers. The PEER block allows a controller to write register data to as many as 16 different controllers simultaneously.

The S975 is installed directly in an option slot of a 984 Controller chassis. In a 984A or 984B Controller, a 7 card chassis is used. The 984X has option slots in the standard 4 card chassis. A single F connector allows the connection of a coaxial cable to the bottom of the interface.

Refer to the following documents for additional information about installation and application of the MODBUS II network:

Dual RS-232 Modem

The S978 Dual RS-232 Modem is an option module that allows a 984 controller to be used as a slave processor in a MODBUS twisted pair network. The modem is electrically compatible with all MODBUS products and is sized to fit in one slot of a 984 chassis.

The S978 Module contains two modems, which are connected via W979 cable to MODBUS ports on the controller’s Communications Processor.

The S978 accepts digital data from the 984 and modulates it into an FM signal - a form of transmission suited to four wire cable. It transmits the FM signal to the MODBUS master, where it is demodulated to digital data.

Conversely, the MODBUS master transmits digital data, which gets modulated to an FM signal on its way to an S978 Modem. The S978 demodulates the signal to digital data and sends the data to the 984.

For more information see manual:

Integrated Control Processor

The C966 Integrated Control Processor (also known as the CoPro) is an option module that extends the processing capabilities of a 964 controller. It provides the power to solve problems that are difficult or inefficient to do in ladder logic.

The CoPro runs standard and customized C routines that can be called by relay logic in the 964. It provides increased system speed via multiprocessing, a flexible multitasking capability, and system expandability. Up to three CoPro modules can be installed in a 964 controller using a P933 power supply.

There are two versions of the C966 - the AM-C966-003, which contains the standard ICP features, and the AM-C966-004 which contains both the standard and optional features. Both modules appear the same except that the AM-C966-004 has a Mass Storage Device (MSD) 50 pin connector. It also has a 24 pin IEEE 466 connector for interface with an IEEE device or device controller. Both are located on the bottom of the module.
