Acknowledging an error
In the VersaSafe system, the errors of the IC220SDL963 as well as those of the
corresponding island satellites must be acknowledged via the IC220SDL963.
After removing the cause of an error, the diagnostic message must be acknowledged. To
do this, set the corresponding bit in the “Dev
-Ackn-
LPSDO” r
egister (see Section
"IC220SDL963 system handling in various control systems" on page 80).
WARNING
Acknowledgment may result in a hazardous system state
With the exception of a few special cases, the acknowledgment of an error immediately
returns the safe input or output to the operating state. Before acknowledging an error you
must, therefore, make sure that the acknowledgment will not cause the machine to switch
to a dangerous state.
When planning the machine or system, make sure that acknowledgment is only possible if
the danger zone is visible.
