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
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 CP1L-EL/EM CPU Units.
