Frequently Asked Questions (FAQ)

• Is the IC695CMU310 suitable for SIL 2 or SIL 3 safety-rated applications?
• No, this module is designed for process redundancy (high availability) rather than functional safety ratings like SIL 2 or SIL 3.

• Can I use the serial ports for programming while the redundancy link is active?
• Yes, the RS-232 and RS-485 ports support SNP protocol for communication with the programmer during operation.

• What happens to the program data if the main system power is lost?
• The CPU utilizes 10MB of battery-backed RAM and 10MB non-volatile flash memory to preserve logic and variables.

• Does this CPU support complex mathematical calculations?
• Absolutely, the IC695CMU310 features native hardware floating-point support for advanced PID loops.

• How do I initiate a hardware reset or operation change?
• Use the integrated 3-position switch on the front panel to toggle between CPU operating modes manually.
