Software - OPC
The Matrikon OPC Server for Modbus provides connectivity to MODBUS compliant devices such as any PLC, RTU, DCS. The server connects to multiple devices using one or more protocols at the same time. Each read/write with the devices is optimized to maximize throughput.
The server has been tested with hardware from vendors such as ABB, Emerson, Honeywell, Koyo, Schneider (Modicon), Triconex, Yokogawa, and many others.
