For networking, communication
PLC networking and communication can be very strong, and new networking construction is constantly launched.
PLC can be connected with personal accounting machine for communication. It can participate in programming and control PLC, so that PLC can be used more conveniently.
In order to give full play to the effect of the accounting machine, a computer can be used to control and handle multiple PLC, and 32 can be used. Also, one PLC can communicate with two or more accounting machines to communicate information to complete more monitoring of PLC control system. PLC and PLC can also communicate, can one-on-one PLC communication, several PLC communication, can be more than dozens, hundreds.
The integration of PLC automation system with advanced communication technology can improve the module assembly function and activate the management of various production links. During this period, I / O module technology, communication management module technology, location management and analog quantity related module technology can be used to monitor and control the instrument and equipment in real time by using the control statement on the basis of strict control of production process to a certain extent. Generally, the analog quantity control system formed after the integration of PLC and communication technology helps to improve the accuracy of the overall control work. For example, in the field of automatic control in industrial production, using such technology and equipment can fully understand the heating information, cooling information and heat preservation information in the heat treatment process, and control it reasonably, It is very difficult to realize the function of heat treatment process in traditional equipment and system.
