Module major error

What does 2443H mean?

A major error has occurred within a module, regardless of specific "CPU Module Operation Setting at Error Detected" parameters explicitly configured to stop. This error indicates a serious condition that significantly impacts module functionality and system operation. If the "Direct change setting" is enabled, the system might continue operation without stopping, but the error itself will persist.

• A major fault condition occurred in a module.
• A module was physically removed or experienced a failure during operation while "Direct change setting" was enabled.
• The module's operation setting at error detection might not be explicitly configured to stop for this type of major error.

Click steps to track your progress.

1. 1

   Verify the "Direct change setting" parameter at [Parameter] -> Module model name -> [CPU Parameter] -> "RAS Setting" -> "Online module change setting".

2. 2

   Before removing a module, ensure the external power supply input to the module is shut off.

3. 3

   If the error remains and affects the system with "Direct change setting" enabled, set it to "Disable" and perform an online module change using special relays and special registers.
