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.

A pressing device for fixing a workpiece onto a worktable, comprising:
- a supporting member extending in a first direction and comprising first and second ends opposite to each other in the first direction and first and second sides opposite to each other in a second direction normal to the first direction;
- a pressing arm connected to the first end of the supporting member and being capable of rotating between a closed state and an opened state with respect to the supporting member, wherein a space for receiving the workpiece is formed between the pressing arm and the supporting member when the pressing arm is in the closed state;
- a first driving assembly arranged on the first side of the supporting member and configured to drive the pressing arm to rotate between the closed state and the opened state with respect to the supporting member;
- a locking assembly arranged on the first side of the supporting member near to the second end of the supporting member and configured to lock the pressing arm when the pressing arm is in the closed state;
- and
- a second driving assembly coupled to the second side of the supporting member and configured to drive the supporting member to move in the second direction.
