Hello Huss1122, As jacek d suggested
And he is absolutely right. But let's dig a little bit into your problem. Your tag "manual setpoint" is a configuration tag of some control system. Configuration tags must not be changed programmatically, they should be constants or changeable by the process operator only. |
