Part III FP Instructions
22.2 Setting the communication parameters
CPU: Setting the communication parameters for the COM ports
During PROG mode: via system registers (see page 714)
via DIP switches (see page 715) (for FP10SH only)
During RUN time: F159_MTRN (switch communication mode (see page
717) with 16#8000)
SYS1 (see p
age 980) with FP-Sigma and FP-X
SYS2 (see p
age 993) with FP-Sigma and FP-X
MCU: Setting the communication parameters for the COM ports
During PROG mode: via MCU dialog
via DIP switches (see page 718) (for FP2/2SH MCU
only)
During RUN time: via F159_MWRT_PARA (see page 719)
F159 (see page 717) (switch communication mode
with 16#8000)
Getting the COM Ports via the Input (X) Flags (see

Setting the CPU's Communication Parameters
22.2.1.1 Setting the CPU's COM Ports in PROG Mode via System Registers
For a general description on setting the system registers, please refer to the online help under setting the
system registers.

Procedure
1. Double-click "PLC" in the navigator
2. Double-click "System Registers"
3. Double-click "COM Port"
The communication ports occupy different bit positions of the same system register, so individual
settings for each communication port are possible.
To make settings for the TOOL port, select "TOOL Port" under "System Registers".
The number of the system register for the respective settings may vary according to the PLC type
used.
Make settings for the communication mode, communication format, baud rate, station number, and receive
buffer if necessary.
