[0031] Please refer to Figure 1The embodiment of the utility model provides a multifunctional debugging device, including a human-computer interaction function module 100, a control module 200, a first electrical signal line 400, a second electrical signal line 410, a switching button and a relay, wherein the control module 200 is connected to the human-computer interaction function module 100; the first electrical signal line 400 connects the control module 200 and the device to be debugged 300, the second electrical signal line 410 is connected in parallel with the first electrical signal line 400, and the second electrical signal line 410 is connected to the high potential of the control module 200; the switching button and the relay are connected to the second electrical signal line 410, the normally closed contact of the relay is arranged on the first electrical signal line 400, and the normally open contact of the relay is arranged on the second electrical signal line 410; wherein the control module 200 is used to turn on the first electrical signal line 400 and output a low level when the switching button is disconnected, and the control module 200 is used to turn on the second electrical signal line 410 and output a high level when the switching button is closed.

[0032] SA01 is a switch button used to switch the high potential and low potential input to the device to be debugged 300. The normally closed contact of the relay is open by default, and the circuit is connected. The normally open contact of the relay is closed by default, and the circuit is disconnected. After the relay coil KA01 is energized, the normally closed contact opened by default will be closed, and the circuit will be disconnected. The normally open contact closed by default will be opened, and the circuit will be connected.

When SA01 is pressed, the relay coil KA01 is at the low level of the PLC output point above and at the high level below, the relay coil KA01 is energized, and the relay coil KA01 is energized. After energization, the normally open contact KA01-1 of the KA01 relay can be turned on, and the normally closed contact is closed and disconnected, that is, the second electrical signal circuit 410 is turned on, and the first electrical signal circuit 400 is disconnected, that is, the circuit on the left side of the figure is turned on, and the circuit on the right side is disconnected, and a high level is output to the debugging device. The control module 200 controls the output low level and the high level connected to the second electrical signal circuit 410, so that the relay coil KA01 is energized, and what is actually input into the debugging device is a high level.

By controlling the output point of the control module 200 in the human-computer interaction function module 100, the output point of the control module 200 outputs a low potential by default. When the input signal of the device to be debugged 300 is at a high potential, closing the switch button SA01 can realize the input of a high potential. The multifunctional debugging device can be configured according to the interface of the device to be debugged 300, thereby realizing the adaptation to a variety of debugged devices.

The control module 200 controls the output of the low level and the second electrical signal line 410 to access the high level, so that the relay coil KA01 is attracted, so that the actual input into the debugging device is a high level.

[0047] When the input signal of the device to be debugged 300 is at a low potential, configure the signal association parameters of the PLC controller and the device to be debugged 300 in the HMI touch screen. By controlling the output point of the PLC controller in the HMI touch screen, the output point of the PLC controller outputs a low potential by default. When the input signal of the device to be debugged 300 is at a high potential, close the switch button to achieve high potential input.
