Laszlo Simon is the Engineering Manager for the TEVA API plant in Debrecen, Hungary. He had a project that sounded simple enough. Connect new control applications through several OPC stations to an existing SCADA network. The plant was already running large YOKOGAWA DCS and GE PLC control systems, connected to a number of distributed SCADA workstations. However, Mr. Simon did face a couple of interesting challenges in this project:
After searching the web, Mr. Simon downloaded and installed the OPC DataHub. Very quickly he had connected the DataHub to his OPC servers and determined that he was reading live process data from the new control systems. He was also able to easily set up the OPC tunnelling link between the OPC server stations and the SCADA workstations, by simply installing another OPC DataHub on the SCADA computer and configuring it to connect to the OPC server stations.
"I wanted to reduce and simplify the communication over the network because of our firewall. It was very easy with OPC DataHub." said Mr. Simon after the system was up and running. Currently about 7,000 points are being transferred across the network, in real-time, using the OPC DataHub. "In the future, the additional integration of the existing or new OPC servers will be with OPC DataHub."
