Safe digital outputs
The safety module has safe positive switching digital outputs, which can be used as fol-
lows:
– For two-channel assignment:
– For single-channel assignment:
Technical data
For the technical data for the safe outputs, please refer to page 10-4.
Parameterization
The individual safe digital outputs of a safety module can be parameterized differently. This
means that the outputs can be adapted to various operating conditions and different safety
integrity levels (SIL, SIL CL, Cat., PL) can be implemented.
In order to achieve a high level of error detection, the test pulses must be enabled. If this
is not possible for the connected loads, the test pulses can be disabled. However, in this
case error detection is reduced.
For information about parameterization, please refer to "Parameterization of the safe
Diagnostics
Diagnostics are provided via both the local diagnostic indicators and the diagnostic
messages, which are transmitted to the controller.
For information about the diagnostic messages of the outputs, please refer to "Safe digital
– Four two-channel outputs
– Eight single-channel outputs
The safety integrity level (SIL, SIL CL, Cat., PL) and error detection that can be achieved
depend on the parameterization, the structure of the actuator, and the cable installation
(see "Connection examples for safe outputs" on page 6-1).
CAUTION: Diagnostic data is not safety-related
The diagnostic data is not safety-related. This data must not be used to execute safety-
related functions or actions.
