The General Electric IC695CMU310 is a specialized Max-ON Hot-Standby Redundancy CPU designed for the PACSystems RX3i control platform. This module provides high-availability processing capabilities for critical industrial applications, ensuring seamless control transitions between master and backup units.

Features

• Max-ON Hot-Standby Redundancy support for high-availability systems.
• 10 Mbytes of battery-backed user memory and 10 Mbytes of non-volatile flash memory.
• Two independent, isolated serial communication ports (RS-232 and RS-485).
• Supports Modbus RTU Slave, SNP, and Serial I/O protocols.
• Typical Boolean execution speed of 0.195ms per 1000 instructions.
• Supports up to 512 program blocks (maximum 128KB per block).
• Integrated hardware handshaking (RTS/CTS) for RS-232 communication.

Applications

The IC695CMU310 is engineered for demanding environments where system uptime is critical. Typical applications include:

• Boiler Systems: Providing logical control and safety monitoring for large-scale industrial boilers.
• Fuel Loading: Managing complex fuel transfer processes at chemical terminals and oil depots.
• Process Control: Monitoring analog outputs and tracking equipment status in metallurgical and chemical manufacturing.
• Infrastructure: Supporting redundancy requirements in power supply and signal control systems for metro and transport networks.

Technical Specifications

Installation Guidelines

• Ensure the RX3i universal backplane is properly grounded before installing the module.
• Always power down the backplane before inserting or removing the CPU module to prevent electrical damage.
• The module occupies a single slot in the RX3i rack.
• Ensure adequate ventilation around the rack to maintain operating temperatures within the 0 to 60 degC range.
• Use shielded cables for serial communication ports to minimize EMI interference, especially in high-noise industrial environments.
• Handle the module using ESD-safe practices to protect internal circuitry.

FAQs

What is the primary function of the IC695CMU310?

The IC695CMU310 is a high-availability CPU designed for Hot-Standby redundancy, allowing a backup controller to take over operations from a master controller within a few logic scans without interrupting I/O states.

Does this module support non-volatile memory?

Yes, it features 10 Mbytes of battery-backed RAM and an optional 10 Mbytes of non-volatile flash memory for program storage.

Is this module suitable for safety-critical systems?

No, the Max-ON redundancy configuration provided by this module is not intended for SIL 2 or SIL 3 safety-rated applications.
