Plc controller provider today: Human-machine interface refers to the field of human and machine in information exchange and functional contact or mutual influence or interface said human-machine bonding surface, information exchange, functional contact or mutual influence, refers to the hard contact and soft touch of human and machine, this bonding surface includes not only the direct contact of the point line surface, but also the role of space for information transfer and control at a distance.

Reasonable Structural Type: There are two structural types: main module and extended module. The average price of each I/O point of the integral PLC is cheaper than that of the module type, and the volume is relatively small, which is generally used in the small control system with a fixed system process; The function expansion of module plc is flexible and convenient, and there is a large choice in the number of I/O points, the ratio of input points to output points, the type of I/O modules…etc, and the maintenance is convenient, generally in more complex control systems.
Frequency principle: That is, according to the frequency of dialogue interaction of the management object design the human-machine interface hierarchical order and dialogue window display position of the list, etc., to improve the frequency of monitoring and access to dialogue. Importance principle: That is, in accordance with the importance of management objects in the control system and the global level, the design of the human-machine interface of the main and secondary menus and the location and prominence of the dialogue window, which helps managers to grasp the importance of the control system, the implementation of good control of the sequence of decisions to achieve optimal scheduling and management.
Consider the typical problems in interface design: To design any interface, we must generally consider four aspects: system response time, user help mechanism, error message handling and command mode. System response time is too long is the most complained about in the interactive system, in addition to the absolute length of the response time, the user is concerned about the difference in response time of different commands, if too much disparity in the user will be difficult to accept; user help mechanism should be integrated, to avoid the superimposed system leads to the user to help a guide and have to browse a lot of irrelevant information; error and warning information must be selected user understandable The error and warning messages must be user-friendly, accurate terminology, and should also provide some suggestions for error recovery as much as possible. In addition, the display of error information, if supplemented by auditory (ringing), visual (special color) stimulation, it is more effective; command mode is best to menu and keyboard commands coexist for the user to choose.
The Third Step: Selecting Type of HMI Panel With the project and market demand and technology innovation, general resistive screen has no meet the new needs of the market and the high requirement of customers, thus deriving a new series of touch screen products, that is multi touch capacitive hmi, its high definition, highest bright, no drift, anti-scratech, supporting multi-touch to achieve special page effect. It is similar to our Apple iPhone, which is very popular in the market. If you are interested, you can have a try Mochuan Drives capacitive hmi panel type. Or to require the special operation temperature for the working environment.
It is good to choose a brand according to the needing of the customers or the market. But it is not for selecting a brand to decide, or more about to focus on its performance parameters, and to be used the functions achieved. Actually there is an attractive story behind the famous brand. So to choose a brand, try to achieve high practicality, to avoide waste one’s talent on a petty job. For example, Siemens, Mitsubishi, Proface, Panasonic brand…etc with a good performance, but before decision to select them, should consider, how many performance of HMI panel will be used for the project? Whether the cost paid matches the performance used on the project? Find more details at mochuan-drives.com.
How To Solve Communication Failure Between HMI Operator Interface And PLC? When communication fails, some customers guess that it may be a problem with the touch screen all-in-one machine or the interface. Online simulation is to bypass the touch screen, use the PLC to connect directly to the computer, use our configuration software, connect the PLC’s own communication cable to the computer, conduct online simulation and see if the project can communicate.
The Macro instructions of HMI Human Machine Interface are based on C language and the system is developed on Linux. There are multi-types of HMI panel, mainly three types, multi touch capacitive hmi panel, plastic shell enconomic resistive hmi touchscreen panel and metal shell wide-temperature resistive touch screen and small home screen to meet different requirement from application scenarios and market needing. There are rich serial port such as rs485, rs232, rs422, ethernet etc to meet the master and slave to use. Mochuan human machine interface manufacturer suppors the size from 4.3inch to 32inch.
