r10151.0...2 CO/BO: SI digital inputs status (processor 2) / SI DI status P2
CU240E-2 DP F Access level: 3
CU240E-2 F
Can be changed: -
Units group: -
Min

Description: Displays 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.
Bit field: Bit Signal name
00 F-DI 0
01 F-DI 1
02 F-DI 2
Dependency: Refer to: p9501, p9601, p10117, p10150
Note: F-DI: Failsafe Digital Input
If a safety function is assigned to an input (e.g. via p10122), 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 parameter-
ization (refer to p10140) 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.
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.
