MPS, MRD and MPP usage:
1. When writing a program in ladder format, programming tools automatically add all MPS, MRD
and MPP instructions at the program conversion stage. If the generated instruction program
is viewed, the MPS, MRD and MPP instructions are present.
2. When writing a program in instruction format, it is entirely up to the user to enter all relevant
MPS, MRD and MPP instructions as required.
