1.6.14.1 How GT Link Functions
With GT link, communication is performed via RS485 by passing a token. The GT that
received the token performs necessary communication with the PLC and transfers the token
to the next GT in ascending order.
Station numbers should be specified in both the GT and PLC. Station no. 0 should be
assigned to ensure optimal boot speed. Do not assign the same station number to more than
1 unit.
GT link control device area
GT station numbers are allocated to the control device area for GT link. Turning on the bit that
corresponds to the GT station no. on the PLC side enables the GT link connection.
