Precautions on the Parameter Setting

(1) Station number setting
The following explains how to set the station numbers for the master station and device stations.
Specify the station numbers according to the following conditions.
• 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. (
• When the number of occupied stations in a module is two or more, set the start station number.

● 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.
