(1)Communication interface setting by Utility

The communication interface setting can be changed on the Utility's [Communication Settings] after writing [Communication Settings] of project data.

For details on the Utility, refer to the following manual.

GT User's Manual

(2)Precedence in communication settings

When settings are made by GT Designer3 or the Utility, the latest setting is effective.

(3)When changing Stage No. and Slot No. Change these settings with the PLC CPU turned OFF, and then reapply the power to the PLC CPU and GOT.

Failure to do so may generate a system alarm (No.487).
