Content of the processing result [D]
● Execution results are stored in the area of one word.
● The execution result code in the low byte is valid when the process in-progress flag of bit 15
is zero.
0: Process done
1: In-progress
Process in-progress flag
0: Normal completion
1: The communication port specified by UNITSEL instruction is invalid
2: Setting error
3: Mode change error
4: Communication port occupied
5: Change request parameter inconsistency (At the start/end of the
setting process, parameters specified by operands are inconsistent)
6: 16 or more SEND, RECV, GPTRNS, pGPSEND, and pPMSET
instructions are used simultaneously. (Note 1)
Execution result code
Execution result flag
0: Normal completion
1: Abnormal completion
(Note 1) Execution result code "6" is enabled for the pPMSET instruction.

Program example 1 (PMSET 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 PMSET instruction, it is necessary to turn ON the execution condition of the PMSET
instruction until the end of processing, and turn OFF the execution condition at a scan in
which the end of data transmission is confirmed.
