Description
Set the GT station no. to which you wish to transfer the GT configuration.
Be sure to assign the station no. 0 to one GT unit!
The address where information regarding GT link is stored (see "How GT
Link Functions" on p. 55).
In both cases, writing to the PLC always has high priority, and the GT must
obtain the token before it can communicate.
 Display priority. each GT station completes all command and
response operations necessary for its screens before passing the token
to the next station.

Operation priority: the GT station processes 1 operation at a time,
then passes the token to the next station.
You can select whether pressing a momentary switch establishes
exclusive communication between that GT station no. and the PLC. During
"exclusive communication", there is no communication with other GT
stations.
You can select whether pressing any touch switch establishes exclusive
communication between that GT station no. and the PLC for the time
specified. During "exclusive communication", there is no communication
with other GT stations.
Until the station obtains the token, it is in "stand-by mode" and cannot
communicate. Activating this option displays a message indicating this.
