Inverting IO Bool Signals with Automation Builder and AC500
Is there an option in Automation Builder to invert a boolean signal that is connected to an IO module? In Control Builder when using the D810 input card there is a property for each IO variable to invert the signal. This property can be very useful when programming failsafe signals. I am looking for the same option in Automation Builder when using a DI524.
Thats the best solution and most commonly used thing.
That simply read the Field IO as "Normally Open" , later in your Codesys program just press CTRL+N or right Click " NEGATE".
It will invert your desired signal.
But recommended for signals like "EMERGENCY" to make it "NORMALLY CLOSED" on hardware basis.
