Technical data
For the technical data for the safe inputs, please refer to page 62.
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.
Important
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 35).
For information on parameterization, please refer to
"Parameterization of the safe outputs" on page 31.
Diagnostics
Diagnostics are provided via both the local diagnostic indicators
and the diagnostic messages, which are transmitted to the
controller.
For information on the diagnostic messages of the outputs, please
refer to "
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.
Requirements for controlled devices/actuators
The error detection of the module varies depending on the parameterization. This results
in specific requirements for the actuators.
•
If the outputs are parameterized with test pulses, the output circuits are tested by
test pulses at regular intervals. These test pulses are visible at the output and can
trigger undesirable reactions with quick responding actuators.
