GT_LinkControlDevice_DUTGT_LinkControlDevice_DUTThis is a predefined DUT with overlapping elements. The DUT can be used for communication between the PLC and a touch terminal of the GT series.
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. Be sure to assign sequential station numbers beginning with 0 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.

Description |
|---|---|
Connected GT designation area |
The bit corresponding to the GT station number for which communication is occurring turns ON on the PLC. If one unit is damaged, it can be disconnected by turning the corresponding bit OFF. NOTE This area must be specified on the PLC. |
Connected GT monitor area |
The status of the GT touch terminals for which communication occurs properly can be monitored. |
Exclusive GT designation area |
The GT with the designated station number occupies communication with the PLC by turning on this bit. This is used to prioritize the operation or display of the GT with a specific station number. The response time of the GT with the designated station number decreases. GT touch terminals with other station numbers cannot perform communication. |
Exclusive GT monitor area |
The bit for the GT station number where the token currently resides. |
