Error Clear Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Error clear function

This function clears all the existing errors at once.
Error clear of only specific remote head module
Operate the specific remote head module and clear the errors of the specific remote head module.
■How to clear errors
Errors can be cleared in the following way.
• Using the engineering tool: Clear errors with module diagnostics of GX Works3. ( GX Works3 Operating Manual)
The event history of error clear using the engineering tool is stored in the connected remote head module.
• Using SM/SD: Clear errors by operating SM/SD.
1.
Check the detected error with 'Latest self-diagnostic error code' (SD0).
2.
Eliminate the cause of the detected error.
3.
Turn off and on 'Error reset' (SM50).
■Precautions
Note the following precautions when using the error clear function.
• Since the function clears all of the currently detected errors at once, errors that should not yet be cleared may be cleared.
• Executing this function does not remove the cleared errors from the event history.
• For an error which occurred by a module other than the target remote head module of error clear, the error cause cannot be
eliminated even though the error is cleared using this function. For example, when "Module verification error" (error code:
2400H) or "Module major error" (error code: 2450H) occurred, the error cause cannot be eliminated even though the error
is cleared in the remote head module using this function. To eliminate the error cause, clear the error of the target module
and reset the remote head module.
