Data type Function
 Communication port
 Must be a constant

FP-X, FP
 PLC communication ports:
Value: SYS_COM1_PORT or SYS_COM2_PORT or
SYS_TOOL_PORT
 MCU communication port:
ANY16
Value: 16#xx01 (COM1), 16#xx02 (COM2)
xx = slot number (hexadecimal) of the MCU (e.g. 16#0001:
COM1 in slot 0, 16#0A02: COM2 in slot 10, 16#1401: COM1
in slot 20)
Other PLCs:
The command will be compiled to F144_TRNS, which works
on the COM port of the CPU (the parameter d_Port will be
ignored)
