GE IC695CRU320-BB Redundancy CPU

GE IC695CRU320-BB Redundancy CPU

The PACSystems* RX3i Redundancy CPU can be used to perform real time control of machines, processes, and material handling systems. The CPU communicates with the programmer and HMI devices via a serial port using SNP Slave protocol. It communicates with I/O and smart option modules over a dual backplane bus that provides: 

 ▪ High-speed PCI backplane for fast throughput of new advanced I/O. 

 ▪ Serial backplane for easy migration of existing Series 90*-30 I/O.

Features 

 ▪ Hot standby (HSB) redundancy. Two redundant units make up a redundancy system. Each unit requires one Redundancy CPU (IC695CRU320) and a redundancy Memory Xchange module (IC695RMX128/228) configured as a redundancy link. 

 ▪ Contains 64 Mbytes of battery-backed user memory and 64 Mbytes of non-volatile flash user memory. 

 ▪ Provides access to bulk memory via reference table %W. 

 ▪ Configurable data and program memory. 

 ▪ Programming in Ladder Diagram, Structured Text, Function Block Diagram, and C. Refer to PACSystems RX7i & RX3i CPU Programmer’s Reference Manual, GFK-2950. 

 ▪ Supports auto-located Symbolic Variables that can use any amount of user memory. 

 ▪ Reference table sizes include 32Kbits for discrete %I and %Q and up to 32K words each for analog %AI and %AQ. 

 ▪ Supports most Series 90-30 modules and expansion racks. For a list of supported I/O, Communications, Motion, and Intelligent modules, refer to the PACSystems RX3i System Manual, GFK-2314F or later. 

 ▪ Supports up to 512 program blocks. Maximum size for a block is 128KB. 

 ▪ CPU firmware may be upgraded in the field. 

 ▪ CPU supports firmware upgrades of modules in its backplane. 

 ▪ Two serial ports: an RS-485 serial port and an RS-232 serial port. 

 ▪ Ethernet communications via the rack-based Ethernet Interface module (IC695ETM001). For details on Ethernet capabilities, refer to PACSystems RX7i & RX3i TCP/IP Ethernet Communications User Manual, GFK-2224. 

 ▪ Time Synchronization to SNTP Time Server on Ethernet network when used with Ethernet Release 5.0 or later. 

 ▪ Compliant with EU RoHS Directive 2002/95/EC using the following exemptions identified in the Annex: 7(a), 7(c)-I, & 7(c)-III.

Hot Standby CPU Redundancy Features

 ▪ Supports single and redundant Ethernet remote I/O LANs through Ethernet Network Interface Unit (ENIU) modules 

 ▪ Supports simplex and redundantly controlled PROFINET remote IO (requires firmware version 8.00 or later) 

 ▪ Survives any one single point of failure 

 ▪ Bumpless switching o Synchronized CPUs o One scan switching o Transfer data size up to 2Mbytes; selected in CPU hardware configuration and in variable properties 

 ▪ Supports two redundancy communications links 

 ▪ Online repair of failed component 

 ▪ Online programming 

 ▪ Redundancy Memory Xchange Module o Manual toggle switch for role switching, which transitions control from the active unit to the backup unit o Redundancy status LEDs   

▪ Application-initiated role switching to switch the active unit to backup status 

 ▪ Redundancy status bits and message logging 

 ▪ Memory error checking and correction (ECC) single bit correcting and multiple bit checking 

 ▪ Background diagnostics

HSB Control Strategy

 ▪ Active unit does not automatically switch to primary on resynchronization 

 ▪ Critical control data plus all redundant outputs must be included in the output data transfer 

 ▪ Bumpless switchover from active unit to backup unit
