Value status

Properties
In addition to the diagnostics alarm and the status and error display, the F-module provides
information about the validity of each input and output signal – the value status. The value
status is entered in the process image along with the input signal.
Value status for digital input and output modules
The value status is additional binary information of a digital input or output signal. It is
entered in the process image of the inputs (PII) at the same time as the process signal. It
provides information about the validity of the input or output signal.
The value status is affected by a short-circuit and the plausibility check.
