automatically during END processing.
*2 Data in the programming tool input area can be turned on or off by the following:
•Test operation of a programming tool
•Writing data from the network module
•Writing data from an external device using the MC protocol
*3 Data in the output (Y) device memory can be turned on or off by the following:
