17 RAS FUNCTIONS
17.1 Self-Diagnostics Function
Error Clear
This function clears all the existing continuation errors at once.
Errors that can be cleared
How to clear errors
Errors can be cleared in two ways:
■Using the engineering tool
Clear errors with the module diagnostics function of engineering tool. (GX Works3 Operating Manual)
■Using SM/SD
Clear errors by operating SM/SD.
1. Check SD0 (Latest self-diagnostics error code) to identify what errors are detected.
2. Clear the cause of each of the currently detected continuation errors.
3. Turn off and on SM50 (error reset).
Precautions
This section describes some precautions to take when using the error clear function:
• Since the function clears all of the currently detected continuation errors at once, errors that should not yet be cleared may
be cleared.
• Use the RST instruction to reset each annunciator individually.
