This paper focused on the same bottom set of field devices, and designed two kinds of field-bus control system, one is PROFIBUS, and another is the Interbus. Applied the OPC technology to realize the information exchange between two bus systems, and applied the PC configuration software, to monitor equipments on the spot. The whole monitoring system included the monitoring program and OPC server program. The monitoring program is no longer included with the specific hardware communication part. The communication monitoring program and hardware are realized by OPC server software, when the system needs to be modified, only need to modify the OPC corresponding part. If the system needs to expand and communicate with the outside world, just need to expand the OPC. After many times field operation, proved the monitoring system of two OPC bus technologies was stable, reliable, and timely control reaction. |
