 A maximum of 31 units can be connected via serial communication. Port numbers from 0 to 31 can be set on the [Device
Setting] dialog of the editor; however, depending on the controller, port numbers exceeding 32 may be available. In such
a case, use the station number table to enable communications with devices of port No. 32 or greater.
 It is easier to specify port numbers for each network in the field by making the screen for setting the port number when
creating the screen program. In this case, it is not necessary to transfer the screen program again.
