The IC695CRU320 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.
▪ Configurable data and program memory.
▪ Programming in Ladder Diagram, Structured Text, Function Block Diagram, and C.
▪ Supports auto-located Symbolic Variables that can use any amount of user memory.
▪ Supports most Series 90-30 modules and expansion racks.
▪ 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).
▪ 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.
