Generic Modbus Interface

 

Many different vendors of industrial equipment and software provide Modbus compatibility. The RTU may interface to any such devices. Examples include DCS and SCADA systems, as well as equipment whose native protocols are not supported.

 

The steps generally necessary for connecting such systems with the RTU are:

 

 

Each of the steps above will need to be performed according to the equipment vendor's instructions. To date, this approach has successfully interfaced to TI/Siemens, Bristol Babcock, Westinghouse, and General Electric controllers, as well as several SCADA systems.
