Mitsubishi Electric · MELSEC iQ-R Series
A critical error has occurred within a module. This error indicates a serious condition that significantly impacts module functionality, and the "Critical" setting is configured to stop the CPU. If the "Direct change setting" is enabled, the system might continue operation without stopping, but the error itself will persist.
Click steps to track your progress.
Verify the "Direct change setting" parameter at [Parameter] -> Module model name -> [CPU Parameter] -> "RAS Setting" -> "Online module change setting".
Check the "CPU Module Operation Setting at Error Detected Critical" parameter setting within System Parameter -> I/O Assignment Setting (each module).
Before removing a module, ensure the external power supply input to the module is shut off.
