5SHY4045L0004 3BHB021400R0002 3BHE039203R0101 GVC736CE101 Temporarily replace the field input signals with manual switches to manually check and verify the PLC input terminals one by one. the indicator light of the PLC input terminals is on, indicating normal; on the contrary, you should check the wiring or the I/O point is bad. Module in the output power supply is good, check all PLC output terminal indicator is fully lit. PLC input terminal indicator is lit, said normal. If the PLC input terminals are lit, it means it is normal, otherwise, we should check the wiring or the I/O points are bad.

5SHY4045L0004 3BHB021400R0002 3BHE039203R0101 GVC736CE101 System commissioning should first connect the power supply, external circuits and input/output terminals according to the control requirements, and then load the program in the PLC and run the PLC for commissioning. Connect the PLC with the field equipment. Comprehensively check the entire PLC control system before formal commissioning, including power supply, grounding, device connection lines, I/O wiring and so on. In the case of ensuring that the entire hardware connection is correct, you can send power.

5SHY4045L0004 3BHB021400R0002 3BHE039203R0101 GVC736CE101 Set the operating mode of the PLC control unit to “RUN” to start operation. Repeated debugging to eliminate possible problems. In the debugging process can also be based on the actual needs of the hardware to make appropriate changes to match the software debugging. Should maintain a long enough running time so that the problem is fully exposed and corrected. Most of the debugging is the control program problems.
