Program example 2 (pPMSET instruction)
● This program sets 12 words of communication parameters for COM1 port of CPU with built-
in SCU, which are stored in the area starting with Data Register DT0. The processing result
is stored in DT100.
● For the pPMSET instruction, when the execution condition arises, the parameter change
processing is performed only once.
■
Program example 3 (PMSET instruction, specification by PLC link parameter)
● This program sets 26 words of communication parameters for COM1 port of CPU with built-
in SCU, which are stored in the area starting with Data Register DT0. The processing result
is stored in DT100.
