A display device includes a control substrate provided in the display device, a first connecting part provided on the control substrate and connecting a controller to the control substrate, the controller configured to control the display device, and a second connecting part provided on the control substrate and connecting a user interface unit to the control substrate, the user interface unit connected to an external device.

Display device

A controller is attached to a back face of a display device. The controller includes: a housing; a control unit removably accommodated in a slot formed in the housing and configured to control the display device; a backboard provided inside the housing on the interior side with respect to the direction of insertion of the control unit and connected to the control unit; and a second connector connected to a first connector provided for the display device to establish connection between the backboard and the display device.

Controller

A display-equipped controller includes a display device, a first junction configured to electrically connect the display device and a main board, a radiator disposed opposite from the display device with respect to the main board, an attaching structure attaching the main board and the radiator to the display device, a support structure disposed between the display device and the main board and configured to detachably support a control board, and a second junction configured to electrically connect the main board and the control board supported by the support structure.

Display-equipped controller

An electronic device has a heat sink configured to cool an electronic component on a circuit board. The heat sink and the circuit board are joined by snap-fitting.

Electronic device

In a control system, a controller and a plurality of input/output units are daisy-chained, and each of the input/output units detects a phase difference between a phase of received serial data and a phase of a reference clock, outputs a determination signal if the phase difference exceeds a threshold value, and records the output frequency of the determination signals. The controller acquires the frequency of the determination signals recorded by each of the input/output unit and specifies a noise mixture route based on the acquired frequency of the determination signals.

Control system

A numerical control system exchanges input/output signals between a numerical controller and an IO unit and the IO unit includes a first control unit that changes an idle signal output from the IO unit using an input signal as a trigger to a specific waveform pattern signal and when the specific waveform pattern signal is received, transmits the specific waveform pattern signal to a former side. The numerical controller includes a second control unit that outputs an interrupt signal when the specific waveform pattern signal is received.

Numerical control system

A matrix key input interface has key common signal lines and key data signal lines wired in a matrix and key switches disposed at positions where the key common signal lines intersect the key data signal lines. The key data signal lines are periodically monitored while key scan signal is not output to any of the key common signal lines. Based on the results of monitoring, an earth fault is detected in key common signal lines or key data signal lines.
