SignalInReal & SignalInBool Function Block Status Show Red Color When Online
I have a problem about Control Builder M Professional (System 800xA):
1. I use Function Block "SignalInReal" on Control Builder M Profressional (system 800xA) to monitor Analog Input Instrument.
2. My Program Shows no Error when I compile it. (See Screenshot 92)
3. If I'm simulating my program, My SignalInReal Function Block shows Red Color. (See Screenshot 93)
4. My "Red SignalInReal Function Block" didn't affect any other Function Block in my program. for example my "Red SignalInReal FB" didn't affect operation of ValveUni Function Block etc.
a. Why is this happen?
b. How to Solve it?
