Deltav redundant opc server With redundant OPC servers, you don’t have to worry about a failure of an OPC server or the Application Station interrupting your data transfer and causing costly downtime. I am running 3 VMs in a WORKGROUP (Proplus and a redundant APP node (APP001) with OPC DA Server and OPC Mirror enabled). DeltaV also offers an OPC UA server embedded in the PK Controller, providing easy access directly to the information inside the controller, in a robust redundant platform and eliminating the need for a workstation to provide OPC UA communications. Redundant OPC Data Access servers provide highly reliable data transfer between DeltaV systems and OPC client applications by using a pair of Application Stations with an active and standby server, automatically switching over if the active fails to prevent interruptions. Then you can license OPC Tags as before and OPC UA Client signals with a new OPC UA Client DST license. . Used in conjunction with the redundant DeltaV OPC Data Access servers, you can increase protection against single point OPC Server hardware and software failures. Hi, I am trying to run a test of the Redundant OPC DA Server to see if the OPC client-server connection is working. How have you configured that for redundancy purposes? The DeltaV™ OPC Data Access Server provides a fast and efficient means for transferring data between the DeltaV system and OPC Data Access client applications. Native DeltaV Redundant OPC Servers Seems the simplest and most Emerson supported method. lkghiyniqvxfjwerkeipekttuqywczdqztmqfbjpnhndtwugqgvpezqoplndekjwalrtiat
