Greetings,
When the Analog Output card halts, do you get any errors on Hardware Editor?
If yes, could you please share it with us?

Redundant Freelance Controller AC900F is connected via CI840A to S800 IO Cards, among them are our Analog Output Cards that is AO810\AO815\AO895 & AO890.
The analog output cards are controlling control valves with 4-20mA output.
the control valves stops\halts at a position(for example 40%) and does not varies(change) until we reset the power.
