Outline of operation
● Communication parameters of the COM port of the unit is changed with a user program.
● Set communication parameters to be changed within [n] words from the area starting with
[S], and execute the PMSET/pPMSET instruction, to issue the setting change request to the
unit.
● While the requested change is being processed, bit 15 of the processing result storage area
[D] turns ON. When the process is completed, it turns OFF.
● The processing result is stored in the area specified by [D]. If there is any abnormality, bit 14
of [D] turns ON. The error code is stored in low bytes of [D].
● By reading setting parameters using the PMGET instruction, and setting parameters to be
changed using the PMSET/pPMSET instruction, the settings can be simplified.
