TEVA combines tunneling and aggregation to network OPC data through a firewall

Project objectives

Sector:

Pharma

Connect new control applications through several OPC stations to an existing SCADA network.

Challenges

The OPC servers and SCADA systems were on different computers, separated by a company firewall. This makes it extremely difficult to connect OPC over a network, because of the complexities of configuring DCOM and Windows security permissions.
Each SCADA system needed to access data from all of the new OPC server stations. This meant Mr. Simon needed a way to aggregate data from all the OPC stations into a single common data set.

Result

After searching the web, Mr. Simon downloaded and installed DataHub® software. Very quickly he was able to connect a DataHub instance to each of his OPC servers, and determine that he was reading live process data from TEVA’s new control systems. He was also able to easily set up OPC tunneling links between the OPC server stations and the SCADA workstations, by simply installing another DataHub instance on each SCADA computer and configuring it to connect to the OPC server stations. This unique combination allows him to view data from both OPC servers on either SCADA system
