Universal controller external to internal setpointi

I am using an universal controller to control flow valve, part of the process that i begin with an internal setpoint of 50 then shift to external setpoint of 70 for 1 min then return to 50 internal, but when i return from external to internal the sp remains 70 !

There is a parameter "Set point tracking" in 3rd Parameter mask of Controller Function Block. Change it on SPI as adjusted. This should solve your problem.

This option exist to avoid Set Point conflicts when changing from external to internal mode.
