This control system is provided with a controller, a controller which is a loopback communication device, a first communication route, and a second communication route. The controller generates and transmits control frames to slave devices. The controller performs loopback communication of the control frames. In the first communication route, multiple slave devices are connected between the controller and the controller using communication cables. In the second communication route, the first controller and the second controller are connected over a communication cable.

The presently disclosed technology relates to networked control of machine tools. An example system can use messages as means for transmitting intention and status in a networked control system. Illustratively, requests for actions or requests for measurements and status are passed across the network as messages rather than discrete signals. This can greatly ease machine expansionnew functions may be implemented by adding new messages on the network and adding new distributed controls to handle the new function hardware.

The invention relates to a modular conveyor system, comprising multiple individual conveyor modules, wherein an individual conveyor module comprises at least one conveyor device, at least one power supply, at least one actuator for driving the conveyor device, an output unit for the control of the actuator and an integrated control unit, wherein the integrated control unit has a computing unit for processing information and a communications unit, and wherein the communications unit is designed to carry out the communication of the individual conveyor modules with a central control system, on the one hand, and/or the communication of the individual conveyor modules with one another, on the other hand, in such a way that the communication of the individual conveyor modules with one another is implemented at two logical communication levels. The invention further relates to a method for controlling modular conveyor systems.
