I bind a tag to a alarm set point so operator can change it in run-time. The problem is each time the gateway reset the alarm set point tag reset to zero. I want this new value of the tag is retentive and save by ignition.
One solution is use Transaction group but I should do this for each alarm I create manually. I want to define this in UDT and when I make instance it’s done automatically.(like alarm,history setting of UDT)
Usually there should be a check box in properties of tag to make it retentive.
Does anyone know to handle this?
