OPC DA, or "OLE for Process Control - Data Access", is a set of classic standards and specifications used in industrial automation and process control systems. It is a communication protocol that enables data exchange between industrial automation devices and software applications, primarily for real-time data access and monitoring.
The Listener allows you to retrieve tag values on the OPC DA Server.
The Action Agent allows you to publish the supplied tag values and timestamps on the OPC DA Server.
This redistributable must be installed on the Stream Host server if the OPC DA environment is not hosted on the same server.
Please contact XMPro if you're looking for an older version of this Agent.
