Start test:
Each time the safety module (=SMX module) is switched on, the input element must be tested
in direction of the Low signal status (defined Safe State), e.g. by actuating the Emergency
Stop button or a door lock after the system has been started.
Operational / organizational tests:
Apart from the previously mentioned diagnostic measures for the SMX modules, cyclic testing
can be performed within the application. These tests can also be used when assessing the
DC.
Note:
Operational/organizational tests can also be used for a combination of hardware inputs and
functional inputs (input information transferred via standard field bus). However, an exclusive
use of functional inputs is ruled out in this context (combination of two or more functional
inputs).
The SMX modules therefore ensure far reaching diagnostics functions for the partial input
system. These are performed permanently or optionally (cross-shorting monitoring by means
of pulse identifier).
