Precautions
■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 "Network Configuration Settings" under "Basic Settings". ( Page 60 Network
Configuration Settings)
• If an empty station number is set without setting a reserved station, the station is detected as a faulty station in 'Data link
status of other stations' (SW0080 to SW0083).
• The station numbers need to be consecutive, but wiring does not need to be performed in the order of station number.
• Set the start station number when the number of occupied stations is two or more.
■Station number duplication
If a station number other than the start station number is already in use in the master/local module, it is detected.
Local station
(station No.: 1, number of occupied
stations: 4)
Remote device station
(station No.: 4, number of occupied stations: 2)
If a start station number is in use, it is not detected. (The station number 0 of the master station is detected if it is in use.)
Check whether the station number of the station where a data link error has occurred is not already used for other stations
using 'Data link status of other stations' (SW0080 to SW0083).
Ex.
For the following case (a local station (station No.1 with the number of occupied stations of 4) and a remote device station
(station No.1 with the number of occupied stations of 2)), the station number duplication is not detected.
