Input Voting
Digital and analog modules are processed (voted) this way:
Valid Modules | Description | ||
3 | 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
HART®
and process measurements pass the integrity checks.Provide Feedback
