Appendix F
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 insulated NT-AL001-E, and do
not use the CP1W-CIF11. If the NT-AL001-E is used, the total transmission distance for the whole trans-
mission 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.
