How to check industrial automation equipment
Check all circuits. Check if there is any open circuit in the circuit, especially if the wire in the wire slot is broken by the wire slot. Inspect the air tube for damaging creases. Check if the hydraulic hose is clogged.
When checking the circuit at this step, use the necessary multimeter, adjust to the buzzer file, and check the path of the loop. If the trachea has a serious crease, replace it immediately. The hydraulic tubing should be replaced.
After ensuring that the above steps are correct, the fault may appear in the controller, but it can never be a program problem! First of all, don't be sure that the controller is destroyed. As long as there is no serious short circuit, the controller has short-circuit protection inside. The general short circuit will not burn the controller.
First, check if there is a device with high frequency interference near the controller. If so, move away immediately. If outdoors, high-intensity lightning can also cause the controller to not work properly in an instant. In this case, first remove all possible interfering devices and then restart the controller.
Secondly, if the restart is invalid, check if the controller wiring is loose and there is a bad contact.
Finally, if the wiring is correct. Determine if there is a problem with the memory card of the PLC. Replace a new card and download the program to check if the previous memory card is faulty. |
