RedundancyMaster increases the reliability and availability of OPC data by allowing multiple OPC Servers to be configured into redundant pairs. Each redundant pair seamlessly appears as a single OPC Server to any OPC Client application. RedundancyMaster can be added to an existing server/client application without any reconfiguration of the application, keeping your processes going with out any down time.
OPC Data Access (OPC DA) technology has proven to be reliable in virtually every possible situation requiring consistent data access to devices and systems. However, there are other factors that can jeopardize the integrity of a system, some being software, hardware, and even the human element. By using OPC redundancy technology you can make these systems more reliable and efficient.
To fill this need for added system reliability, Kepware has developed RedundancyMaster. RedundancyMaster resides on your OPC client machine and facilitates connections to a Primary and Secondary OPC server on the system's networks by 'hooking' into the OPC calls made between the client and the server. If for any reason the OPC client loses its communications link or an item quality goes bad with the primary OPC server, RedundancyMaster will drop the primary and promote the secondary OPC server on your network - reducing system down-time and saving you money.
RedundancyMaster can be a drop-in application that does not require you to make any changes to your OPC client or server applications. Its intuitive configuration takes only minutes and will allow you to have a Redundant OPC system running with no headaches. Simply browse and select your primary and secondary OPC servers, and the system is up and running. We have built in features such as email notification, object and link monitoring, and diagnostics logging. In the situation where you need multiple redundant OPC server pairs that utilize the same OPC server vendor, we have added the capability to alias* the ProgID (Program ID) of the OPC server.
