5 PROCEDURE BEFORE STARTING THE DATA LINK
5.5 Station Number Setting
The following explains how to set the station numbers for the master station, local
station, standby master station, remote station and intelligent device station.
For details on the station number settings, refer to Section 8.2.3.
Specify the station numbers according to the following conditions:
(1) Assign sequential station numbers.
Station numbers can be specified regardless of the order in which the stations are
connected.
For a module occupying two or more stations, specify the first station number.
(2) Specify unused station numbers as reserved stations.
If unused station numbers are not specified as reserved stations, they will be
handled as data link faulty stations (can be checked with special link registers
SW0080 to SW0083).
(3) Specify unique station numbers.
If duplicate station numbers are specified, an installation error occurs. (Error
codes are stored in SW0069)
[Setting example] One station was skipped when station numbers were specified.
