Serial Communications Section 6-3
Here, we will describe Host Link and No-protocol communications.
Note The CJ1W-CIF11 is not insulated and the total transmission distance is 50
meters max. If the total transmission distance is greater than 50 meters, use
the insulated NT-AL001 and do not use the CJ1W-CIF11. If only the NT-AL001
is used, the total transmission distance can is 500 meters max.

Converts received FINS com-
mands into CompoWay/F com-
mands and transfers them on the
serial communications path.

Up to ten words per Unit can be
shared by up to nine CPU Units,
including one Polling Unit and
eight Polled Units.
An RS-422A Converter can be
connected to the RS-232C port on
each CPU Unit to communicate
via RS-422A/485, or two CPU
Units can communicate via an RS-
232C connection.
The Serial PLC Links can also
include PTs as Polled Units via NT
Links (1:N) combined with CJ1M
CPU Units.
