OPC redundancy software RedundancyMaster

OPC server

RedundancyMaster increases the reliability and availability of your 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 client/server application without any reconfiguration of the application, keeping your processes going without any downtime. 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.
