10 common faults and solutions
2018/04/12
Industrial control machine is a general term of a tool that uses the bus structure to detect and control the production process, mechanical and electrical equipment and process equipment. Industrial control machine has important computer attributes and characteristics, such as computer CPU, hard disk, memory, peripherals and interface, and operating system, control network and protocols, computing power, friendly man-machine interface. The industrial control machine often operates in a harsh environment, and the safety requirements for data are higher. Therefore, the industrial control machine is usually reinforced, dust proof, moisture proof, corrosion proof, radiation prevention and other special designs.
In the actual use process, the industrial control machine will have some faults due to hardware or software problems, the causes can be roughly divided into five categories: one is the fault, including power instability, electromagnetic interference, high or low working temperature, or even lightning strike; the second is software fault; third is the fault caused by normal aging; four is the electrical connection fault; five is the human fault.
Organize the common faults and solutions of 10 industrial control machines.
Q: Unable to install the device driver correctly
1, check whether the driver is correct and the latest;
2. Whether the driver needs the support of the operating system;
3. Whether the resources occupied by other equipment are in conflict with the resources occupied by the equipment that need to be driven;
4, if the peripheral equipment, change a slot and reinstall the drive;
5. Replace the equipment and reinstall the driver program.
Q: After the industrial control machine is powered up, the power supply works normally, and there is no response from the motherboard
1. Remove the peripheral plug card insertion and the connected equipment, and see if it can start?
2. If not, you can remove the memory, see whether the alarm?
3. Check the CPU work, is it normal?
4. Replace the motherboard and check whether the motherboard is normal.
Q: The PCIE expansion network card network port light is on, but it cannot communicate
1. Check whether the network card is inserted and intact
2. Whether the equipment manager is identified
3. Whether the drive is installed normally
4. The command line can restart the network related configuration and enters the following command
netsh interface Teredo set state disable Line change
netsh intter set state enterpriseclient Line change
Check the service status and enter "netsh int Teredo show state"
