Kepware Redundancy Master

OPC Data Access (OPC DA) technology has been proven to be reliable in virtually every industrial environment requiring consistent data access to devices and systems. However, there are other factors that can jeopardize the integrity of a system, including software, hardware, and even human error. By using OPC redundancy technology, you can help make these systems more reliable and efficient.

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 with the primary OPC server or a user-specified condition is met (such as an item is not receiving updates, a specific item value is met, or the quality of an item is set to bad), RedundancyMaster will drop the primary OPC server and promote the secondary OPC server on your network—reducing system downtime and saving you money.

RedundancyMaster is 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 easily establish a redundant OPC system. Simply browse and select your primary and secondary OPC servers, and then your system is up and running. RedundancyMaster includes 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. (Aliasing may require minor OPC client modifications.)
