It features a 700 MHz processor and 10 MB of user memory, providing robust processing power for complex automation tasks.

Features

• Designed for PACSystems RX7i rack-mounted frameworks.
• Supports Hot Standby CPU Redundancy for high-availability systems.
• 700 MHz clock speed for efficient logic execution.
• 10 MB of battery-backed RAM and 10 MB of non-volatile flash memory.
• Integrated Ethernet interface for networked communication.
• Error Checking and Correction (ECC) to detect and correct single-bit memory errors.
• Physical memory protection switch to prevent unauthorized logic changes.
• Diagnostic LEDs for real-time operational status monitoring.

Applications

This CPU module is primarily utilized in large-scale industrial automation systems requiring high reliability. It is commonly deployed in process control, material handling, and critical machine monitoring where system downtime must be minimized through redundant processing.

Technical Specifications

Installation Guidelines

• Ensure the system power is disconnected before installing or removing the CPU module from the RX7i rack.
• The module is designed for chassis mounting; ensure it is fully seated in the backplane slot to maintain proper electrical contact.
• Maintain adequate ventilation around the rack to ensure the ambient temperature remains within the 0 to 60 degC operating range.
• Follow standard ESD (Electrostatic Discharge) precautions when handling the module to prevent damage to internal components.
• Verify that the battery is properly installed and connected to ensure the retention of calendar data and variables during power loss.
• Route communication cables away from high-voltage power lines to minimize EMI interference.

FAQs

What is the switchover time for the IC698CRE020 in a redundant configuration?

The maximum switchover time from failure detection to the backup CPU taking control is one logic scan, with a minimum of 3.133 milliseconds.

Does this module support legacy I/O?

Yes, the IC698CRE020 is compatible with Series 90-70 discrete and analog I/O modules, as well as standard VME modules.

What is the purpose of the physical switch on the module?

The physical toggle switch allows the user to set the module to a "Memory Protect" position, which prevents accidental or unauthorized modifications to the stored control logic.
