5.2 Parameterization of the safe outputs
The individual outputs of a safety module can be parameterized differently and thus
achieve different safety integrity levels (SIL, SIL CL, Cat., PL).
Two-channel If the outputs are operated via two channels, the following fixed assignment applies:
– OUT0_Ch1 to OUT0_Ch2
– OUT1_Ch1 to OUT1_Ch2
– OUT2_Ch1 to OUT2_Ch2
– OUT3_Ch1 to OUT3_Ch2
Single-channel If two-channel operation in the external wiring of the outputs is not required, the outputs
can be parameterized in such a way that they operate independently of one another
(single-channel).
Parameterization All safe outputs must be parameterized individually. The parameterization options are
described in Table 5-1.
Table 5-1 Parameterization of outputs
Parameterization Value range Remark
OUT0 - OUT3
Assignment Not assigned
Assigned
The outputs that are not assigned are disabled. However, the
monitoring of these outputs remains active.
Output Single-channel
Two-channel
In two-channel operation, the assignment of the outputs to one
another is specified and cannot be parameterized.
Switch-off delay for stop
category 1
Disabled
Enabled
Disabled (default): No switch-off delay.
Enabled: The outputs are switched off once the parameterized
switch-off delay has elapsed.
Please observe the notes below this table.
Switch-off delay for stop
category 1
1 to 63 Time conversion according to the parameterization of the "Value
range of switch-off delay for stop category 1" parameter.
Permissible value range:
OUT0 to OUT3:
150 ms to 630 s
Accuracy: -5% of the parameterized value - 2 ms/+0 ms
Please observe the notes below this table.
