13. System setup for serial communications
When an actual PLC performs serial communications, it is necessary to set
communications parameters to the PLC’s I/O memory areas. Also for the
CX-Simulator, use the CX-Programmer to set Serial Communications
mode, Start bits, Data length, Stop bits, Parity, Baud rate, etc., according to
the manuals for each Serial Communications Unit.
Note
DIP switch setting for “RS-232C port communications parameters” (pin 5) is
fixed to “Use parameters set in the PLC Setup” (OFF).
For CPU Unit’s RS-232C port (Port 2) settings, refer to 7-1-2 PC Setup in
CS/CJ Series Operation Manual, and for Serial Communications Board/Unit
settings, refer to 4-2 Setup Area Allocations in CS/CJ Series Serial Commu-
nications Boards/Unit Operation Manual (W336).
Note
When using the RS-232C port (Port 2) on the CPU Unit, if a protocol not sup-
ported by the CX-Simulator is set in PLC Setup, communications cannot be
performed.
