Elaborate and implement a safety
concept!
The use of the module requires a safety concept for your machine or system.
These include the hazard and risk analysis and an inspection report (check‐
list) to validate the safety function, refer to
chapter 14 "Checklists" on page 69
The target safety integrity (SIL acc. to IEC 61508, SILCL acc. to EN 62061 or
the performance level and category acc. to EN ISO 13849-1) results from the
risk analysis. The determined safety integrity depends on how the module is
to be wired and parameterized in the safety function.
Validating hardware and parame‐
terization
Perform a safety validation in the complete system after each safety-relevant
change.
Ensure the following points are observed using your test report:
●
The safe modules are connected to the correct sensors and actuators
●
The parameterization of the safe input and output channels is correct
●
The linking of the variables to the safe sensors and actuators (single-or
dual-channel) is correct.
