Provided is a control system of an industrial machine that can automatically detect the presence or absence of a wiring error at a start-up of a machine, and that prevents a dangerous operation such as high rotation/high torque of a motor from occurring due to a wiring error. A control system of an industrial machine includes: a control unit that controls driving of a drive unit of the industrial machine; a command unit that issues a command to the control unit; and a wiring error detection device that detects a wiring error in a system of the control unit and the drive unit on a basis of a feedback value of actual driving of the drive unit upon a start-up of the industrial machine.

An automatic monitoring system for monitoring the integrity of a wiring having a number of cables, the monitoring system having an integrity measuring unit designed to be coupled to the electrical wires in order to carry out measurements and check for the presence of faults along the electrical conductors, and a detection unit to detect a voltage present in the electrical wires and to enable the integrity measuring unit in case the voltage has a predetermined relation with a voltage threshold, indicating the fact that the electrical load is not powered by the power supply source. The integrity measuring unit has an impedance measuring circuit to apply a measurement signal to a circuit formed by the pair of electrical wires and to obtain a value of the impedance of the same circuit. The integrity measuring unit checks for the presence of a fault depending on the impedance value.

Tools and techniques are described to attach a device to a controller, whereby the controller analyzes the device inputs, looks up information about the device in a database, and then determines which inputs on the device match the defined device inputs. It then may translate information received from the device into an intermediate language. It may also use the information received from the device, the location of the device, and information about the device to create a digital twin of the device.
