2. Example of selective recombination

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.

Pay attention to the programming order so that a branch line does not cross a recombination line.

Before recombination, first program the drive processing of state relays.

After that, program only the transfer processing to recombination state relays.

This rule should be observed to enable inverse conversion into an SFC program.

3. Example of parallel branch

Do not use MPS, MRD, MPP, ANB and ORB instructions in a 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.
