Diagnostics Using the Process Image Input Table

Properties
In addition to the diagnostic information available with the LEDs and module/DP diagnostics,
the module also provides information about the validity of every input signal - the value status.
The value status is entered in the process image along with the input signal.
Value Status of the Digital Input Modules
The value status is additional binary information in a digital input signal. It is entered in the
process image input table at the same time as the process signal and provides information on
the validity of the input signal.
The value status is influenced by the wire break check / short-circuit, chatter monitoring, pulse
stretching and validation check of changeover contacts.
● S7 format with value status
– Input signal is valid: "1
– Input signal is invalid: "0
Value status from the analog input modules
The input values of the analog input modules are stored in the process image of the inputs.
For a measured value, the following value status is entered as input value:
● S7 format
– Input signal is valid: No value status
– Input signal is invalid: "7FFF
