FAQ

Q1: What is the GE Fanuc IC695CMU310-CJ used for?
The IC695CMU310-CJ is a high-availability CPU module used in PACSystems RX3i redundant control systems. It allows two RX3i controllers to operate in a hot standby configuration, providing improved system availability for critical industrial processes.

Q2: What type of applications use the IC695CMU310-CJ?
The module is commonly used in applications requiring continuous operation, such as power generation, process control, fuel handling systems, and other automation systems where controller downtime must be minimized.

Q3: What memory capacity does the IC695CMU310-CJ provide?
The module provides 10 MB battery-backed RAM and 10 MB non-volatile flash memory for storing user programs, configuration data, and application information.

Q4: What communication interfaces are available on the IC695CMU310-CJ?
The CPU includes two isolated serial communication ports supporting RS-232 and RS-485 interfaces. Supported protocols include SNP, Serial I/O, and Modbus RTU Slave communication.

Q5: What is the difference between the IC695CMU310-CJ and earlier revisions?
The CJ revision corresponds to firmware version 5.50. It adds Run-mode Store of Ethernet Global Data (EGD) capability and support for the LREAL floating-point data type compared with previous firmware versions.

Q6: What software is used to configure the IC695CMU310-CJ?
The module is configured and programmed using Proficy Machine Edition, including the Max-ON redundancy configuration tools required for hot standby applications.

Q7: What power supply requirements does the IC695CMU310-CJ have?
The CPU requires approximately 1.0 A at +5 VDC and 1.25 A at +3.3 VDC from the RX3i backplane power supply.

Q8: What should be checked before replacing an IC695CMU310-CJ module?
Before replacement, verify the RX3i backplane compatibility, redundancy configuration, firmware compatibility, battery condition, Ethernet redundancy setup, serial communication settings, and Proficy Machine Edition project configuration to ensure a smooth system recovery.
