Connections to Serial Communications Option Boards
Serial PLC Link Connection Examples
This section provides connection examples for using Serial PLC Link. The communications mode used here is
Serial PLC Link.
Connecting an RS-422A Converter
CP1H CPU Unit
(Polling Unit)
RS-232C Option Board
RS-422A Converter
(CJ1W-CIF11)
Note The CP1W-CIF11 is not insulated, so the total transmission distance for the whole transmission
path is 50 m max. If the total transmission distance is greater than 50 m, use the RS-422A/485
port on the CP1W-CIF12 directly, or the insulated NT-AL001, and do not use the CP1W-CIF11. If
the CP1W-CIF12 or NT-AL001 is used, the total transmission distance for the whole transmission
path is 500 m max.
Connection with an RS-232C Port
RS-232C connection is also possible when using a Serial PLC Link to connect two CP1H CPU Units.
