PCM600 Event Viewer can be used to view the audit trail events and process related
events. Audit trail events are visible through dedicated Security events view. Since
only the administrator has the right to read audit trail, authorization must be used in
PCM600. The audit trail cannot be reset, but PCM600 Event Viewer can filter data.
Audit trail events can be configured to be visible also in LHMI/WHMI Event list
together with process related events.

To expose the audit trail events through Event list, define the

Authority logging

 level parameter via 

Configuration/

Authorization/Security

. This exposes audit trail events to all users.
