5466-31 6 programmable logic controllers play an insignificant role in factory automation. The continuous development of skills is based on a PIC-centric control system
Progress in control function, control level, etc. Together, the requirements for its control method and operation level are also getting higher and higher, so the requirements for interactive operation interface, alarm recording and printing have also become the whole operation
Important content of control system. 5466-316 is particularly important for those industrial control systems with messy process and more control parameters. The presentation of new-generation industrial human-machine interface, about construction
The construction of plc industrial control system completes the above functions and provides a simple and feasible way.
The characteristics and functions of industrial man-machine interface
5466-316 Industrial human machine interface, referred to as hmi, also known as contact screen, is a kind of intelligent operation control display device. Industrial human-machine interfaces to specially planned calculations
The 32-bit risc cpu chip is the center of the system, and the 5466-316 resistance network contact screen is covered with the stn, tft wave crystal display screen or el electroluminescent display. Touch the screen when the resistor is on the network
The resistance and voltage change and the contact position is calculated by software.
The main functions of nmi are: data input and display; Real-time information on the operating status of the system or equipment is displayed; The hmi can be controlled by setting the contact control on the hmi as the operation panel.
Alarm processing and printing; In addition, the new-generation industrial human-machine interface also has simple programming, processing of input data, data login and formula and other intelligent control functions.
When the hmi is used in the plc control system, the communication between the hmi and the plc is conducted by direct link (direct connection) through the serial port. In this method, the hmi directly reads the pIc data or the number as required
Data is written to the appropriate address of the plc. Because of the built-in communication protocol, there is no need to prepare a communication program, just use the plc type that is the communication protocol, and the communication can be completed during operation. Therefore, the use of plc is greatly reduced.
The responsibility of the account program. In the system planning, directly control the components and their corresponding pIc input and output (i/o), register (r), center register (m) address, operation hmi can be active and plc
Exchange data. Directly read or rewrite the content of the plc corresponding address, and change the content displayed on the screen accordingly. Together with the contact operation of the hmi, data can be entered into the corresponding address of the plc.
