Hello Team, 

I used Zenon internal tag (String data type) as a remanent tag and in this randomly the tag value was changed to either 0 or 1 without any manual intervention. So whatever the string value i have entered in internal variable was changed.

This is happening randomly in my project which is developed in Zenon V7.60.

I need to support to permanently resolve this.

Regards,
