5.2 Parameterization of the safe outputs
The individual output pairs of a module can be parameterized differently, which means that
different safety integrity levels (SIL, SILCL, Cat., PL) can be achieved.
Two-channel The following fixed assignment applies for two-channel operation:
– OUT0_Ch1 to OUT0_Ch2
– OUT1_Ch1 to OUT1_Ch2
– OUT2_Ch1 to OUT2_Ch2
– OUT3_Ch1 to OUT3_Ch2
Single-channel For single-channel assignment, the outputs can be parameterized so that they operate
independently of one another.
Parameterization The safe outputs are parameterized in pairs for each connector. Table 5-1 describes the
parameterization options.
Test pulses If the light pulses are disabled, cross-circuits and short circuits cannot be detected when the
output is switched off.
However, outputs parameterized as “Not used” are tested with test pulses.
Observe the additional information: see “Requirements for actuators/controlled devices” on
page 15, see Section 6 “Connection examples for safe outputs” on page 37.

Parameterization Value range Comment
Assignment Not used
Used, single-channel
Used, two-channel
The unused outputs are disabled. However, the monitoring of
these outputs remains active.
In two-channel operation, the assignment of the outputs is fixed.
Test pulses (output
disabled) (in software: test
impulses (output switched
off))
Disabled
Enabled
Enabling and disabling of test pulses. For these test pulses, the
output drivers that are disabled are temporarily enabled for test
purposes (light pulses).
Observe the notes below this table.
Switch-off delay for stop
category 1
Disabled
Enabled
Disabled (default): no switch-off delay.
Enabled: the outputs switch off once the set switch-off delay has
elapsed (250 ms/500 ms/1 s/2 s/4 s/8 s/16 s/32 s/64 s/128 s).
Accuracy:±5% of the set value
Assignment of the switch-
off delay
Two-channel
To channel 2
Either two-channel assignment or assignment to just channel 2 is
possible for the switch-off delay.
The default values are shown in bold .
