When the machine tool is in normal working condition, there is a specific logical relationship between all input signals, output signals and internal memory units in the electronic control system. When the machine tool fails, the conventional logic relationship changes, so that a common fault logic judgment program can be pre-programmed by using this logic relationship, and the running state analysis and fault alarm control can be realized through it.
PLC industrial control technology to achieve communication and remote control research. The communication function of PLC is manifested on the one hand, which can realize mutual communication between PLCs, on the other hand, it can also realize mutual communication between PLC and other intelligent terminals. The PLC generally has a communication interface and a networking module to realize remote control of the PLC.
Industrial competition is becoming increasingly fierce. Domestic industrial production technology keeps pace with international development. In order to enhance their comprehensive competitiveness, industrial enterprises require more comprehensive control over the process of industrial production. At the same time, the progress of innovative thinking and the transformation of theoretical results have added strong conditions for the development of industrial production control technology. The real-time, openness, robustness and reliability of PLC technology strengthen the operational capability of production process control and help to create a common development platform for object control. The government should advocate that industrial enterprises should actively introduce PLC technology into industrial applications. Only in this way can industrial enterprises, such traditional enterprises, be in an invincible position in the fierce market competition.
