8.4 Communication Parameters
The communication parameters are set in the system registers of the PLC. The
communication ports occupy different bit positions of the same system register, so individual
settings for each communication port are possible. Make settings for the communication
mode, communication format, baud rate, station number, and receive buffer if necessary.
During PROG mode:
Use the programming tool to enter settings for the communication port in the system registers.
During RUN mode:
Use the SYS1 instruction to change the communication parameters. Please refer to the
FPWIN Pro online help for detailed information.
The communication mode can be switched using F159_MRTN (see page 169).
