Module Reset Function from Sequence Program

This function resets a module from a sequence program without resetting the PLC or the
master block when the switch settings are changed or an error occurs in the master block.
However, reset is disabled when there is an read module error (when the BFM#A
ON).
Because the PLC is not initialized, operations of other modules are not affected at
all.
The figure below shows a program example for module reset.
