Description

The GE IC698CPE020, also cataloged as the IC698CPE020 CPU Module, operates as a dedicated hardware component for high-speed logic execution and system orchestration within PACSystems RX7i VME64 platforms.

Hardware Specifications

PLC System Architecture and Communication

The IC698CPE020 utilizes high-speed backplane bus communication velocity to manage deterministic I/O updates across the RX7i rack assembly. The CPU maintains full firmware flash compatibility, allowing for seamless integration with updated control software versions. I/O density scaling is facilitated through the support of 32K bits for discrete signals and 32K words for analog data streams. The module architecture supports deterministic network performance via dual-port Ethernet connectivity, enabling simultaneous execution of multiple industrial protocols including EGD, Modbus/TCP, and SRTP, ensuring low-latency communication between the controller and remote field devices.

Frequently Asked Questions

Q: Does the IC698CPE020 support hot-swapping within the VME64 backplane?

A: No, this module must be installed or removed only when the rack power is disconnected to avoid damage to the high-density backplane connector pins and potential corruption of the system bus.

Q: Are the three serial ports galvanically isolated?

A: Yes, the three serial ports (RS232/RS485) are physically isolated to protect the CPU circuitry from ground loops and external transient voltages present in the industrial communication environment.

Q: Is a memory battery required for data retention?

A: The module utilizes 10 MB of non-volatile flash memory to store the user program and configuration data, maintaining integrity during power loss without absolute reliance on a volatile backup battery.

Field Installation Guidelines

• Ensure the VME64 backplane is securely mounted and grounded before inserting the CPU module into the primary slot.
• Use shielded twisted-pair cabling for all Ethernet and serial connections to minimize electromagnetic interference; ensure shields are terminated at the designated chassis ground point.
• Verify proper seating of the module by engaging the front-panel locking levers, ensuring the backplane pins are fully mated without excessive mechanical force.
• Configure the CPU using the specified Proficy Machine Edition software version to ensure compatibility with the internal hardware revision.
• Adhere to standard ESD protocols during handling to prevent damage to sensitive internal microprocessor and memory components.
