Changing Communications Port Settings Using STUP(237) Appendix R
Settings
Note STUP(237) transfers 10 words of data from the DM Area Setup Area. When using the Modbus-RTU
slave mode, the Setup Area is expanded. Before executing STUP(237), use MOV(021) or other instruc-
tions to write the Modbus-RTU settings directly to the DM Area Setup Area for the Serial Communica-
tions Board/Unit. Doing so will allow STUP(237) to transfer all of the expanded DM Area Setup Area to
the Serial Communications Board/Unit.
