Server Redundancy Module (SRM) for GE iFIX

Key Features

The server redundancy is required when your iFIX system includes processes that cannot run simultaneously on both servers. For example:

• Dual iFIX SCADA servers sharing a single serial communications path to multiple RTUs and/or PLCs. Without SRM-2, communications drivers running simultaneously on the dual servers will fail by trying to compete for this single comms path.
• iFIX schedules need to run on just one server in a redundant pair to avoid duplicated actions.
• Third-party applications like Win911 Pager or Catapult OnDemand will create conflict if they run on two servers simultaneously.

How it works
SRM-2 ensures that communications drivers and critical processes run only on the preferred server, avoiding conflicts with processes running in two places at once. SRM-2 monitors the servers over single or dual LAN connections. Failure of a server triggers SRM-2 to automatically start the missing communications drivers and processes on the remaining server. iFIX alarms will alert users to the fail-over.

Key Benefits

• Automation Interface - SRM-2 provides an (OLE) automation interface. This allows it to be controlled from within the iFIX Workspace environment using Visual Basic for Applications (VBA).
• Fail-over notification - iFIX alarms notify operators of fail-over incidents.
• Fail-over recording - In an iPower SCADA system, or iFIX system running Events, the migration of process between servers is recorded in the Events list.
