Part III FP Instructions
ReceiveData
Receive data from CPU or MCU port
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.

FP-X, FP and FP2, FP2SH (V1.4 or later):
 PLC communication ports:
Value: SYS_COM1_PORT or SYS_COM2_PORT or SYS_TOOL_PORT
 MCU communication port:
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)
