Routine maintenance

The daily maintenance and repair of PLC is relatively simple, mainly replacing fuses and lithium batteries, and there are basically no other vulnerable components. Because the random access memory (RAM), counter and auxiliary relay with retention function that store user program are protected by lithium battery, the life of lithium battery is about 5 years. When the voltage of lithium battery gradually decreases to a certain extent, the battery voltage on the PLC basic unit drops to the indicator light, reminding the user that the program supported by lithium battery can be retained for about one week, and the battery must be replaced, This is the main content of daily maintenance.

The steps to replace the lithium battery are:

■ Before disassembly and assembly, the PLC should be powered on for more than 15 seconds (this can charge the capacitor as the standby power supply for the memory. After the lithium battery is disconnected, the capacitor can supply power to the PLC for a short time to protect the information in the RAM from being lost);

■ Disconnect the AC power supply of PLC;

■ Open the battery cover of the basic unit;

■ Remove the old battery and install the new battery;

■ Close the battery cover.

Note that the battery replacement time should be as short as possible, generally not more than 3 minutes. If the time is too long, the program in RAM will disappear.

In addition, it should be noted that the specified type of product should be used when replacing the fuse.

I/O module replacement

If a module needs to be replaced, the user should confirm that the installed module is of the same type. Some I/O systems allow live replacement of modules, while others need to cut off the power supply. If the problem can be solved after replacement, but the fault occurs after a relatively short time, the user should check the inductive load that can generate voltage, and may need to suppress its current spike from the outside. If the fuse is easy to burn out after replacement, it may be that the output current of the module exceeds the limit or the output equipment is short-circuited.

The fault diagnosis of PLC is a very important problem and the key to ensure the normal and reliable operation of PLC control system. This paper discusses the common fault diagnosis methods. In the actual work process, various adverse factors on PLC should be fully considered, and regular inspection and daily maintenance should be carried out to ensure the safe and reliable operation of PLC control system.
