6.5 Value status (CQ HSC0)
Properties
In addition to the diagnostic messages and the status and error display, the F-module makes
available information about the validity of the count and status values in the feedback
interface. The value status is available in the process image along with the count and status
values for the channel.
Value status for the F-TM Count module
The value status is additional binary information provided in the feedback interface. It is
provided in the process image of the inputs (PII) at the same time as the process values. It
provides information about the validity of the process inputs.
The value status is influenced by channel and module wide diagnostic results.
• 1
B: Valid process values are provided for the channel.
• 0
B: Fail-safe process values are provided for the channel.
If the F-TM Count module input channel is passivated, the fail-safe system always provides
("0") for the count value, measured value, and event and status bits.
Assignment of inputs for the value status in the PII
The input channel of the F-module is assigned a value status (CQ HSC0) in the process image
of the inputs. You can find the assignment in section Address space (Page 60).
Reference
A detailed description of the evaluation and processing of the value status can be found in
the SIMATIC Safety – Configuring and Programming manual
