About the Configuration Tab
To display the Configuration Tab for a Server-to-Server Collector in the Historian Administrator, select a Server-to-Server Collector from the list on the left and click the Configuration Tab.
The table describes the Server-to-Server Collector-specific fields.
Field
Description
Source Server
Designates the Historian Server to use as the Source.
Alarm Replication
Allows you to enable or disable alarm replication. If you enable alarm replication, all collected alarm data will be transferred from the source server to the destination server. If you enable alarm replication, you also enable alarm recovery. However, if you set the Max Recovery Time to zero, no alarm recovery should occur.
Message Replication
Allows you to enable or disable message replication. If you enable message replication, you also enable message recovery. However, if you set the Max Recovery Time to zero, no message recovery should occur.
Calculation Timeout (sec)
The maximum time allowed for a tag's calculation formula to execute before being terminated. The default is 10 seconds.
Max Recovery Time (hr)
The maximum time in hours before now that the collector will attempt to restore data during recovery logic. The default is 4 hours.
Add Prefix to Messages
Allows you to add an identifying prefix to replicated messages, so that they can be easily identified on the destination.
Alarm and Event data will automatically have a prefix added to it with the following syntax:
MachineName_Datasource
For example, if your alarm is forwarded from the server Almserver12 with a data source named OPCAE, the prefix will be Almserver12_OPCAE.
