If a FactoryTalk ViewPoint alarm summary does not show any events, consider the following potential causes and remedies.
If the alarm summary has an active filter, alarms you expect to see may be hidden.
If networking and communications have failed on the host computer, the FactoryTalk ViewPoint server will be unable to communicate with the FactoryTalk Alarms and Events servers.
If the same alarm summary does not show any events, the problem is not in the FactoryTalk ViewPoint but at the lower levels such as the networking and communications.
If the FactoryTalk Alarms and Events server is not running or is not detecting any alarms, the FactoryTalk ViewPoint server will be unable to communicate with it or will receive no alarms.
