7.3.5 Additional notes

In this example, two contacts of the guard switch are connected to a safety input device, which
realizes the error detection. The resulting BOOL signal is mapped to the two input channels of
the SF_GuardMonitoring_1.
The diagnostic information retrieval has not been covered in this example. For this, refer to
Ä Chapter 7.2.5 "Additional notes" on page 345. The input parameter Activate for the dynamic
FB activation has been set to TRUE. However, in an application, this can be replaced by a vari-
able.

Description
Automatic reset allowed when PES is started
No automatic reset, user reset/acknowledge

Automatic reset allowed when PES is started
No automatic reset, user reset/acknowledge
necessary
The discrepancy time between both safety
inputs S_GuardSwitchX is not monitored,
because they are identical and since the
input unit provides one signal of type BOOL
from the contactors.
