How does OPC Expert licensing work, and does a single license cover multiple servers and features like OPC Bridge?
OPC Expert is a platform that bundles multiple modules and capabilities under a single license structure. Features such as OPC Bridge, OPC Tunneler, OPC Redundancy, Archive OPC Data, and OPC Trend Software are all part of the OPC Expert platform rather than separate products requiring individual licenses. You do not need to purchase a distinct license for each OPC server you connect to or for each bridging feature you use.
What the OPC Expert Platform Covers
OPC Expert is designed as a comprehensive toolset for industrial connectivity. When you license OPC Expert, you gain access to the full suite of modules it includes, spanning data bridging, tunneling, archiving, trending, redundancy management, and more. This unified approach means practitioners are not forced to piece together separate tools from different vendors to accomplish common integration tasks.
Connecting to Multiple Servers
OPC Expert supports simultaneous connections to multiple OPC servers, both local and remote. The bridge functionality, for example, allows you to connect to different OPC DA and OPC UA servers at the same time, with each server operating on its own communication thread. There is no per-server licensing requirement built into the platform’s standard operation. You configure as many bridges as your environment requires, including configurations that span thousands of data points across many servers.
Installation and Deployment Considerations
OPC Expert does not require installation and does not modify the Windows Registry. This means the software can be copied and run on any compatible Windows system without triggering licensing complications tied to system modifications. When running OPC Bridge or other features as a Windows service, the same executable handles automated background operation without requiring additional license instances for the service context.
Relevant Tools
OPC Bridge is a feature of OPC Expert that handles real-time data transfer between OPC DA and OPC UA servers, and it operates within the same platform license. OPC Expert as a whole also includes OPC Tunneler for secure cross-network communication, OPC Redundancy for failover management, and Archive OPC Data for data capture and storage, all available under the same product umbrella.
OPC Expert offers a flexible and consolidated licensing model that avoids the overhead of managing separate licenses for each server connection or individual feature.
