Description: Setting for the transfer and evaluation of failsafe digital inputs (F-DI) via PROFIsafe.
The safe state of the selected F-DIs is transferred to the F-control via PROFIsafe. The F-DIs are monitored for
discrepancies. Discrepancy faults can be acknowledged via PROFIsafe.
Dependency: Refer to: p10150
Note: F-DI: Failsafe Digital Input
Description: Display and BICO output for the single-channel, logical and debounced status of the fail-safe digital inputs (F-DI).
The parameter is updated in the SI Motion monitoring clock cycle.
Dependency: Refer to: p9501, p9601, p10017, p10050, r10151
Note: If a safety function is assigned to an input (e.g. via p10022), then the following applies:
- logical "0": Safety function is selected
- logical "1": Safety function is de-selected
The interrelationship between the logical level and the external voltage level at the input depends on the
parameterization (refer to p10040) of the input as either NC or NO contact and is aligned to the use of a safety
function:
With 24 V at the input, NC contacts have a logical "1" level, for 0 V at the input, a logical "0" level.
This means that an NC/NC contact parameterization of 0 V at both inputs of the F-DI selects the safety function, for
24 V at both inputs, de-selects the safety function.
With 24 V at the input, NO contacts have a logical "0" level, for 0 V at the input, a logical "1" level.
This means that for an NC/NO contact parameterization, the level 0 V/24 V selects the safety function, the level 24
V/0 V de-selects the safety function.
F-DI: Failsafe Digital Input
The state of parameter r10151 is delayed by one monitoring clock cycle in relation to r10051.
The parameter is only updated in the following cases:
- if the Safety Extended Functions are enabled by means of activation via F-DI.
- if transfer of the F-DIs via PROFIsafe is enabled (see p9501).
In this case only the F-DIs transferred for PROFIsafe are displayed and updated (see p10050/p10150). All F-DIs
which have not been transferred have a static zero value.
