Station Number Setting

This section describes how to set the station numbers for CC-Link and a master/local module.
(1) Station number setting for CC-Link
For CC-Link, follow the rules below to set the station numbers.
• Set the station numbers not used for other stations. If a station number already in use is set, an error occurs.
• Set consecutive station numbers for stations in the same system.
To set empty station numbers for future use, set the stations as reserved stations. Setting the stations as
reserved stations prevents the stations from being detected as a faulty station. Set reserved stations in the
master station using the network parameter of a programming tool. (
162, Section 8.3.4)
• When the number of occupied stations in a module is two or more, set the start station number.

Ex.
Master station
Station No.0
Setting the station numbers 1 to 3 (number of occupied stations: 3) as reserved stations
Ex.
Master station
Station No.0
● If an empty station number is set without setting a reserved station, the station is detected as a faulty station in Other
station data link status (SW0080 to SW0083).
● The station numbers need to be consecutive, but wiring does not need to be performed in the order of station number.
