Function
STUP(237) writes 10 words of data from S to S+9 to the communications setup area of the Unit with the
specified unit address, as shown in the following table. When the constant #0000 is designated to S, the
communications settings of the corresponding port will be set to default.
The following data is stored in the 10 words from S to S+9.
When STUP(237) is executed, the corresponding Port Parameters Changing Flag (A619.01, A619.02,
or A619 to A636) will turn ON. The flag will remain ON until changing the parameters has been
completed.
Note If the PLC is turned OFF and then ON again after STUP(237) has been used to change the communications
parameters, the new parameters will be retained or will revert to the previous parameters, depending on the
CPU Unit.
