In fact, we are dealing with glass cover, glass or other products that require anti-fingerprint coating. Many manufacturers want to apply anti-fingerprint treatment to their products, and most of them use AF anti-fingerprint coating equipment. When these manufacturers use these anti-fingerprint devices, the PLC control screen parameters display question marks. Many people don't know what the problem is. I don't know how to solve it!
 

　　Don't worry about this problem, the editor Rogen of the AF anti-fingerprint spraying equipment manufacturer Zhenyi shares will tell you one by one!
 

　　First of all, we want to solve this kind of problem on the screen. We don't know how to solve it. We need to troubleshoot the reason for the question mark on the screen of the AF coating equipment. What are the reasons for the question mark on the screen of the equipment?
 

　　1. System disorder
 

　　2. The network cable is not plugged in properly
 

　　3. System problems
 

　　Knowing the above reasons, it is relatively simple to troubleshoot. Then the editor Rogen will tell you how to solve the above problems:
 

　　1. If we encounter the problem of system disorder, we shut down and restart, if it still does not work, we proceed to the second step
 

　　2. If the network cable is not plugged in properly, there will also be a reason for the parameter display question mark, so here we also need to troubleshoot the network cable contact problem. If this step cannot be resolved, we judge that it may be the cause of the system.
 

　　3. If none of the above steps solve the problem, the preliminary judgment may be a system problem. For system problems, please contact the manufacturer in time.
 

　　The above is the problem and solution of the question mark displayed on the screen parameters during the use of AF coating equipment. I hope it will be helpful to you.
