Input Voting

Digital and analog modules are processed (voted) this way:
Valid Modules
Description

The mid-value is used by the application
2
The lower value is used by the application
1
The value is used by the application
0
The previous value is used by the application. A fault will occur after the process safety time (PST).
TIP: For analog output modules, the measured currents are added together since they share the current.
A valid module means the
