Programmable Coprocessor Module (IC697PCM711). For details, see the “CPU Operational Notes“ section on page 15. Communications Coprocessor Module (IC697CMM711) For details, see the “CPU Operational Notes“ section on . DLAN Module (IC697BEM763 For details, see the “CPU Operational Notes“ 

Any BTM (IC697BEM713) used must be at least version H, hardware rev R08 or greater. Any BRM (IC697BEM711) used must be at least version M, hardware rev R13 or greater

Any Genius Bus Controller (IC697BEM731) used must be revision 5.8 or greater, hardware revision G or greater. To obtain this revision of the GBC, you must order upgrade kit 44A751619-G01.

Analog module requirements are as follows: 

IC697ALG230 used must be version F or greater. 

IC697ALG320 used must be version D or greater. 

IC697ALG440 used must be version D or greater. 

IC697ALG441 used must be version C or greater.

■ Hot Standby CPU Redundancy (including new CPU module CRE020). Hot Standby CPU Redundancy is a system in which two PLC CPU units are cooperating to control the same process. There is an Active Unit that is actively controlling the process and a Backup Unit that is synchronized with the Active Unit and able to take over the process should it become necessary. The two units are synchronized when both are in Run Mode and the Backup Unit has received the latest status and synchronization information from the Active Unit and both are running their logic solution in parallel. The Backup unit is a Hot Standby unit, capable of taking over the process. Redundant I/O capability is based on the Genius I/O System. 

■ SNP Serial Protocol - proprietary serial protocol used primarily to communicate with application programs (e.g. programmer software). 

■ Serial I/O Protocol - provides an interface for serial communications through COMM_REQs. 

■ User configuration of serial ports during Stop Mode. 

■ DRUM function block 

■ SWITCH_POS function block 

■ SCALE function block 

■ TMR_THOUS, OFDT_THOUS, and ONDTR_THOUS function blocks – higher resolution timers 

■ LAST_SCN status bit (%S2) 

■ RUN/STOP switch configuration – allows the switch on the PLC to be configured as a memory protect switch rather than run/stop. 

■ Service Request 29 - Read Power Down Time 

■ Service Request 45 - Skip Next I/O Scan 

■ New Reflective Memory Communication modules IC698CMX106 (non-redundant) and IC698RMX106 (redundant)

Racks 

 PACSystems RX7i Racks set the pace for the latest PLC technology. They are built to   support the high-power PACSystems power supplies along with the latest technology in   the PACSystems CPUs. The VME64 backplane provides up to four times the bandwidth of existing VME based systems for faster I/O throughput. The VME64 base supports all standard VME modules including I/O and VMIC modules

Power Supplies 

 PACSystems RX7i Power Supply modules simply slide into the PLC rack just like I/O, and they work with any PACSystems CPU. The low capacity power supply delivers up to 100W total output without forced air cooling. The high capacity power supply accommodates applica tions requiring more power, providing up to 350W total output, and requires forced air cool ing, provided by a fan tray mounted on the bottom of the rack. PACSystems power supplies also have built-in protection for autoranging power factor corrections as well as overcur rent, overvoltage, and overtemperature fault conditions

PACSystems features a variety of communications options for distributed control   and/or I/O, supporting a wide range of communication protocols and configurations. These communication modules are easy to install and quick to configure. Some  distributed I/O communications modules allow for numerous remote drops or additional racks, while others provide an interface for GE products up to 7500 feet away from the controller.
