Error clear of all remote head modules
Operate the master station and clear the errors in all the connected remote head modules.
This operation clears all the currently occurring errors at once so that none of them can be detected.
■How to clear errors
Errors are cleared in the following way using the master station program or the engineering tool.
1.
Eliminate the causes of the errors in the remote head modules.
2.
Check that the bit corresponding to each remote head module is 0, using 'Baton pass status of each station' (SW00A0 to
SW00A7) of the master station.
3.
Turn on 'Error clear' (SB000F) of remote head module from the master station. When 'Error clear' (SB000F) is turned on,
each remote head module clears the errors and the errors will not be detected.
4.
Turn off 'Error clear' (SB000F) of remote head module from the master station. When 'Error clear' (SB000F) is turned off,
each remote head module becomes able to detect the error.
■Precautions
• After the errors are cleared, always turn off 'Error clear' (SB000F).
• 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.
