With the popularization of automation and the continuous development of industrial control skills, there are more and more application scenarios of industrial computers.
1. After the IPC is turned on, the motherboard self-test is successful, but the system cannot be booted from the hard disk
1. Press the "Del" key to enter the CMOS hard disk to see if the parameter settings and boot order are correct.
2. After booting with an optical drive or floppy drive, check whether the hard disk of the industrial computer has a boot system or whether the hard disk is properly partitioned and the boot partition has been activated.
3. Use FDISK/MBR commands.
2. The memory self-test of the industrial computer does not match the actual capacity after the computer is turned on
1. Check whether the motherboard video memory (motherboard integrated graphics card) is shared with the motherboard memory, which will separate a part of the memory as video memory.
2. Check whether the memory is small-particle memory (that is, the capacity of each chip on the memory is less than 16M, such as 128M memory should have 8 chips), because some old chips do not support large-particle memory, and only half of the capacity is displayed after plugging in.
3. Because the motherboard uses a special CPU, it occupies part of the memory as an instruction decoder for CPU instruction set conversion, so the memory capacity does not match.
3. After the industrial computer is turned on, it will crash if it cannot fully enter the system, or a blue screen may appear
1. Check whether there is a conflict between system resources.
2. Whether there is a fault in the BIOS settings.
3. Replace the memory module.
4. Partition and format the hard disk of the industrial computer from scratch and install the operating system.

The causes and solutions of EVOC industrial computer crash
1. The industrial computer "crashes" due to hardware reasons
Reason analysis: When the industrial computer processes too many on-site signals transmitted by the PLC, the CPU frequency of the industrial computer is low, and the memory is small, so it is impossible to identify and process so many signals together, so that these signals "crash" and form an industrial ...

The difference between serial ports RS-232, 422, and 485 on industrial motherboards
Serial port is a very common device communication protocol on industrial motherboards, and most industrial motherboards contain more than two serial ports based on RS-232. The serial port sends and receives bytes on a bit-by-bit basis, which is slower than parallel communication on a byte-by-byte basis, but the serial port can be used in the use of a single wire.
