4.10 Safety Integrated commissioning
To parameterize the forced checking procedure (test stop) for the Basic Functions, proceed
as follows:
1. Enter the interval for performing dynamization and testing the safety shutdown paths in
the "Timer" (p9659) field.
Within the parameterized time, the "STO" function must be selected and deselected at
least once. The monitoring time is reset at every STO deselection.
2. Connect the "Test stop required" (r9773.31) signal sink to a digital output or to a bit in the
status word of the fieldbus.
Note
Reset of the timer for the Basic Functions
If when simultaneously using the extender functions, the forced checking procedure (test
stop) is performed, the timer of the Basic Functions is also reset.
While STO is selected by the extended functions, the terminals for the selection of the
Basic Functions are not checked for discrepancy. This means that the forced checking
procedure (test stop) of the Basic Functions must always be performed without the
selection of STO or SS1 by the extended functions. Otherwise the correct control by the
terminals cannot be checked.
Test stop for Extended Functions or Advanced Functions.
Note
If the "Basic functions via onboard terminals" option is active for the Extended Functions, you
must make the forced checking procedure settings both for the Basic Functions and for the
Extended Functions or Advanced Functions.
