If you use Proficy Historian in conjunction with Enhanced Failover, your Proficy Historian Archiver should not be installed on either of the SCADA pair; it should be on a remote machine. Historian Collectors should be running on your iFIX SCADA nodes – both the primary and secondary. Your collectors can be configured as redundant collectors, but they do not have to be. To configure redundant collectors, you use the Proficy Historian Administrator. For more details, refer to the "Using the Historian Administrator" electronic book in the Proficy Historian online help.
Be aware of the following when working with Proficy Historian and Enhanced Failover:
- If you want to collect data and alarms from SCADAs in an Enhanced Failover pair, you can do that in the same way as in previous versions of iFIX. To collect data, use an iFIX native collector or use the Historian OPC collector to the iFIX OPC data server. Put one data collector on each SCADA in the pair. Be sure to collect data by logical node name. To collect alarms, put an alarm collector on each SCADA node.
- Proficy Historian collectors currently do not support Windows Vista. So, if you want to use Enhanced Failover and Proficy Historian, do not install iFIX on Windows Vista.
- Tags are added to the default collector selected on the SCADA node from Configure Historian Server(s) dialog box. To access this dialog box, in the iFIX WorkSpace, in Ribbon view, on the Administration tab, in the Proficy Historian Group, in the Configure Historian list, click Configure Historian Server.
- Only a primary collector can be set as the default collector. Secondary collectors are not available for selection.
- Historical data links are not affected by a SCADA Server failover since they continue to request data from the same Proficy Historian Archiver.
- The Integrated Historian feature for iFIX allows you to add tags only from an active SCADA node.
- With the Integrated Historian feature, iFIX always adds tags as LogicalNodeName.TagName.F_CV except for a text block. For a text block, it is added as LogicalNodeName.TagName.A_CV.
