1.5 Safety of the machine or system
The machine/system manufacturer and the operator are solely responsible for the safety of
the machine or system and the implemented application in which the machine or system is
used. The Machinery Directive must therefore be observed.
Draw up and implement a
safety concept.
In order to use the safety module described in this document, you must have drawn up an
appropriate safety concept for your machine or system. This includes a hazard and risk anal-
ysis according to the directives and standards specified in Section “Directives and stan-
dards” on page 12, as well as a test report (checklist) for validating the safety function (see
“Appendix: Checklists” on page 99).
The target safety integrity level (SIL according to EN 61508, SILCL according to EN 62061
or performance level and category according to EN ISO 13849-1) is ascertained on the
basis of the risk analysis. The safety integrity level ascertained determines how to connect
and parameterize the safety module within the overall safety function.
Within an INTERBUS-Safety, SafetyBridge or PROFIsafe system, the
IB IL 24 PSDO 8-PAC safety module can be used to achieve safety functions with the fol-
lowing requirements:
– Up to SIL 3 according to standard EN 61508
– Up to SILCL 3 according to standard EN 62061
– Up to Cat. 4/PL e according to standard EN ISO 13849-1
Check hardware and pa-
rameterization
Carry out a validation every time you make a safety-related modification to your overall
system.
INTERBUS-Safety: Use the “Validation” checklist in the UM EN INTERBUS-SAFETY SYS
user manual to help you.
Use your test report to ensure that:
– The safe devices are connected to the correct safe sensors and actuators.
– The safe input and output devices have been parameterized correctly.
– The variables have been linked to the safe sensors and actuators correctly (single-
channel or two-channel).
INTERBUS-Safety: Please also refer to the example description in the INTERBUS-Safety
system description UM EN INTERBUS-SAFETY SYS.
SafetyBridge: Please refer to the documentation for the configurable safety module used.
