Whether the program is correct can be determined by observing the on-off of the indicator lights 9 or the output of the industrial touch screen 3 to determine whether the field equipment can operate and act according to the program requirements in actual use, and whether the logical relationship in the program is correct.

[0078] During debugging, analog signals are input into the secondary circuit through the voltage signal generator 6 and the current signal generator 7, so as to simulate various operating conditions that the field device may encounter.

[0079] After the simulation test and the function simulation are completed, the power supply is disconnected, the device is moved to a fixed place, and the universal wheel 20 is folded or fixed. A complete hydroelectric LCU simulation debugging process is completed.
