The prime contractor for the job was in Europe, with an integrator in the Middle East, a planned installation in the Middle East, and a system checkout planned in the United States. In addition to these savings, the open system made system checkout possible.

The use of an open system based on OPC and Modbus generated significant savings in integration time and engineering for the user of the application. The OPC Server automatically updates the HMI with the new values. When the DCS wants to write data, it writes to the Modbus addresses in the OPC server. When the DCS wants to read data from the HMI system, it reads the Modbus addresses in the OPC server that correspond to the data points mapped from the HMI into the OPC server. In the DCS system, the Modbus Ethernet Master interface was configured to connect to the OPC Server over Ethernet, using the open Modbus TCP protocol. Then, in the HMI system, personnel mapped all data points that were to be shared with the DeltaV DCS system (read or write) into points in the OPC server. The customer utilized OPC server software solutions from Software Toolbox, in Matthews, N.C., to bridge the gap between the DCS and HMI systems.įirst, the customer installed Software Toolboxs TOP Server Modbus Ethernet Slave OPC server on the same computer as the HMI-based Building Management System (BMS).
