Abstract
A control circuit for use with a network and a distributed control system. The control circuit incudes a switch module, a communication interface module coupled to the switch module and configured to convert data sampled from industrial field into a format suitable for being transmitted to the switch module via the network, and a controller module coupled to the switch module and configured to receive the converted data from the switch module and process the converted data. The switch module is configured to enable a communication between the communication interface module and external devices outside the control circuit and a communication between the controller module and the external devices.
