Modbus is a simple and robust communications protocol for PLCs and other industrial devices and equipment. The Cogent DataHub supports Modbus TCP, a variant of Modbus used for TCP network communications.
With the Cogent DataHub you can:
Connect Modbus slave devices or PLCs to OPC UA or OPC DA to provide Modbus OPC server functionality.
Monitor and control your Modbus slave from a web-based HMI with a drag-and-drop editor for building pages.
Log your Modbus data to a SQL database, and push data back to the Modbus slave, in real time.
