Safe zone error (SZE)
A pending zone error is transferred to the zone master via a ctrlX SAFETYlink
and is available as sum signal via the error state for zone nodes for further
processing. This sum signal is provided to all zone nodes.

Configuration
To use the safety function "Safe zone error" (SZE), it has to be configured via
the parameter "P-0-3266.0.2, SMO: Configuration of safety zone". The following
configurations can be set individually for each zone node:
● Zone node signals zone error and reacts to zone error (type 1)
● Zone node only signals zone error (type 2)
● Zone node only reacts to zone error (type 3)
● Zone node does not signal any zone error and does not react to zone error
Monitoring function
According to the configuration, the zone nodes react differently to their own
errors and zone errors:
● Type 1
