35.2.6 Program with state relays in branches and recombination
1. Example of selective branch
Do not use MPS, MRD, MPP, ANB and ORB instructions in a transfer processing program with branches and
recombination.
Even in a load driving circuit, MPS instructions cannot be used immediately after STL instructions.
In the same way as programs for general state relays, program the drive processing first, and then program the
transfer processing.
Continuously program all transfer processing.
