The CGR772 is programmed and configured by MS-DOS or Windows programming software to perform real time control of machines, processes and material handling systems. The CGR772 communicates with I/O and smart option (specialty) modules over the rack mounted backplane (IC697CHS750, 790, 791) by way of the VME C.1 Standard format. Supported option modules include all IC697 LAN interface modules, several Coprocessor modules, Bus Controller for IC660/IC661 I/O, Communications modules, and all of the IC697 family of discrete and analog I/O modules.

Typical Hot Standby CPU Redundancy System Configuration User Memory Program and data memory for the CGR772 is provided by a memory board with 512 KBytes of battery-backed CMOS RAM. This memory board is an integral part of the CGR772 and is included with the module. This memory board provides error checking through a CPU checksum routine with detected parity errors being reported to the CPU as they occur. Operation, Protection, and Module Status Operation of this module may be controlled by the three position RUN/STOP switch or remotely by an attached programmer and programming software. Program and configuration data can be locked through software passwords or manually by the memory protect keyswitch. When the key is in the protected position, program and configuration data can only be changed by a programmer connected through parallel communications (that is, via the Bus Transmitter module). The status of the CPU is indicated by the seven green LEDs on the front of the module. 3 96 MHz, 32-Bit Floating Point, 512 KByte Memory Central Processing Unit for CPU Redundancy Applications PLC CPUs November 1999 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 23-3 CPU Redundancy Systems The CGR772 is used as the controller in a CPU Redundancy system. Two redundancy control methods can be configured using the CGR772. The GHS method (IC660/661 Hot Standby) uses multiple single bus IC660/661 I/O networks with one redundant controller in each synchronized PLC. The GDB method (IC660/661 Dual Bus) uses multiple dual bus IC660/661 I/O networks with two redundant controllers in each synchronized PLC. The location of the CGR772 modules in a typical Hot Standby CPU Redundancy system is shown in Figure 1. Installation It is the responsibility of the OEM, system integrator, or end user to properly install the PLC equipment for safe and reliable operation. Product manuals provide detailed information about installation, startup, and proper use of the PLC equipment. The installation manual, shipped with your PLC programming software, describes how to properly install the equipment. If the PLC installation must comply with supported standards, such as FCC or CE Directives, please refer to the Installation Requirements for Conformance to Standards, shipped with the PLC programming software, for additional guidelines. Installation should not be attempted without referring to the applicable Programmable Controller Installation Manual and the Hot Standby CPU Redundancy Manual. Connect the battery to either of the battery connectors on the module. Put toggle switch in the STOP position. Put keyswitch in Memory Protection OFF position. Make sure rack power is off. Install in slot 1 of rack 0. (See Figure 1) Turn on power. The module should power up and the top left (OK) LED should blink. When the diagnostics have completed successfully, the top left LED stays on and the second (RUN) and third (EN) LEDs are off. The fourth (bottom left) LED (MEM PROTECT) is off if the keyswitch is in the OFF position. The CPU is now ready to be programmed (if connected parallel, the CPU can be programmed regardless of key position). After the program has been verified the toggle switch can be moved to the appropriate operation mode position; RUN WITH OUTPUTS ENABLED, RUN WITH OUTPUTS DISABLED, or STOP. The LEDs indicate the position of the toggle switch, memory protection status, status of serial port activity, and the state of the program.

These three ports are accessed by connections on the front of the module for serial interface to the programming computer, or other serial serial devices. Ports 1 through 3 support SNP Slave protocol only. Ports 1 and 2 do not support program Load and Store or Datagrams. For details, see the Important Product Information sheet that ships with the module. Protocols Supported Port 1 Port 2 Port 3 SNP Yes Yes Yes SNPX No No No RTU Not supported Not supported Not supported The programmer connection (shown below) is typically made from CPU serial Port 3 to the serial port on the programming computer, through an RS-422/RS-485 to RS-232 Converter (IC690ACC900) or RS-422 to RS-232 Miniconverter (IC690ACC901). This connection can be made with available cables or you may build cables to fit the needs of your particular application. See the IC697 Programmable Controller Serial Communications Manual for more information on serial communications. Note When configuring a CPU Redundancy system the programmer must be connected to the CPU in the Primary unit to configure the Primary PLC and then moved to the CPU in the Secondary PLC to configure the Secondary PLC.
