This function forcibly clears the output data (remote output RY) to slave stations when
the programmable controller CPU comes to STOP.
Remote output RY refresh device setting in the automatic refresh parameter dialog box
provides the following choices.
When "Y" is specified, the remote output RY is cleared regardless of the parameter
setting.
When specifying any device other than "Y" (e.g. M or L), make parameter setting to
specify whether to refresh or forcibly clear the remote output RY.
For the status of each station at error occurrence, refer to Section 8.2.6.
