The assigned safety state is requested. If longer than 500 ms: the option board detects a
fault.

Inactive
Inactive
The assigned safety function is requested.
It is possible to assign these tasks to each of the digital inputs:
the request of a safety function
the acknowledgment signal
the reset signal
the proximity sensor
It is possible to assign 1 task per digital input. The exceptions are the acknowledgment signal and the reset signal which can be
assigned to the same input.
N O T I C E
If proximity sensors are used, it is not possible to assign safety function features to the corresponding inputs. See 3.6.5 Proximity
sensors.
3.5.3 Output Configuration
The 2 two-terminal digital outputs operate in a two-terminal equivalent mode: the state of both terminals must match each other
within a discrepancy time (see
11.2 Safe Input/Output Data). The external system or systems should make sure that the two termi-
nals are in the same state.
The tasks that can be assigned to each of the digital outputs:
the SSM function output
the SBC function output
simple custom logic
For more information on the SSM and the SBC function outputs, see 6.2.2.3 The STO Function Used with the SBC Function and
6.3.5.3 The SSM Safe Output.
To configure the simple custom logic for an output, select a logical function and desired signals from a configuration group. The
option board uses the selected signals and applies the selected logical function to determine the state of the output.
1. Select the group that contains the desired signal or signals.
2. Select the logical function to combine the selected signals.
3. Select the signal or signals.
If only 1 signal is selected: AND or OR (regardless of which): output = signal. NAND or NOR (regardless of which): output = negative
signal.
See the examples below for signal and output correspondence.
The available logical functions:
AND
OR
NAND
NOR
Only 1 logical function per output can be selected.
