Alarm and Events
When the Remote System object is created, one event collector service is created
automatically and assigned to handle subscription for the remote system. 
A collection definition object is also created for each remote system that is added to
the subscriber system. When an upload is performed event categories are uploaded
to this collection definition object.
Before the first upload the event collector will indicate an error,
OPCAE_STATUS_NOCONFIG. After the first upload the status will be good.
Alarms from the provider system will be collected for objects that have been
uploaded only. Alarm and Event lists on proxy objects will be uploaded together
with their List Configuration and Color Definition aspects.
For large configurations with many provider systems it is possible to add more
collector services and change the default assignment. The event collector group
assignment is changed in the OPC/AE Configuration tab of the System Connection
aspect in the Remote System object.
