Human machine interface wholesale provider today: Determine the task that should be performed by human and computer respectively to complete the system function: There are two ways of task analysis. One is to start from the actual, through the analysis of the original application system in a manual or semi-manual state, it will be mapped to a set of similar tasks performed on the human-computer interface; the other is to study the system requirements specifications to derive a set of user tasks coordinated with the user model and system assumptions. Techniques such as stepwise refinement and object-oriented analysis are also applicable to task analysis. Stepwise refinement techniques can continuously divide the task into subtasks until the requirements for each task are clear; and object-oriented analysis techniques can be used to identify all the objective objects associated with the application and the actions associated with the objects.

Corresponding Functional Requirements: Gemerally, small plc have functions such as logic operation, timing and counting, which can be met for equipment that only needs to be controlled by switching quantity. For systems with switching control as the main and a small number of analog control, an enhanced plc with A/D and D/A conversion units and functions of addition and subtraction arithmetic operations and data transmission can be selected. For complex control, it is required to realized PID calculation, closed-loop control, communication networking and other functions, visual control scale and complexity, and choose mid-range or high-grade plc. However, medium and large PLC are more expensive and are generally used in large-scale process control and distributed control system.
Object-oriented principle: That is, according to the identity characteristics and work nature of the operator, design a human-machine interface that is compatible and friendly. According to their work needs, it is appropriate to display prompts, guidance and help information in pop-up windows, so as to improve the level of user interaction and efficiency. HMI, whether for the field controller or for the upper monitoring and management, the two are closely interconnected, they monitor and manage the field equipment objects are the same, so many field equipment parameters are shared between them and passed to each other. The standardized design of the human-machine interface should be the future development direction, because it really reflects the easy-to-configure, simple, and practical principles of the base, fully expressing the human-centered design concept. A variety of industrial control configuration software and programming tools provide powerful support for the production of a beautiful human-machine interface, and the larger and more complex the system, the more it can reflect its superiority.
In the wisdom of industry, electrical cabinet control equipment is suitable for electric facilities, chemical plants, mechanical plants, plant electrical control, network companies electrical control, site large electrical equipment control, etc., to provide convenient electrical management services for the majority of enterprises. Whether it is a small or large electrical cabinet control equipment, it can easily manage the whole company, the whole enterprise, the whole factory electrical equipment.

Human-machine interfaces exist in all areas where human-machine information exchange is involved. A large number of industrial and commercial use, a simple distinction between “input” (Input) and “output” (Output) two, input refers to the operation of machinery or equipment by people, such as handles, switches, doors, instructions (orders) issued or maintenance, and output refers to the machinery or equipment issued by the notice, such as failure, warning, operating instructions tips, etc., a good human-machine interface will Help users more simple, more correct, more rapid operation of machinery, but also to maximize the performance of machinery and extend the service life, and the market refers to the human-machine interface is more narrowly defined in the software user-friendly operating interface.
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?
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.
Multi-touch capacitive hmi panel is new design and very popular with the market. Why? It is similar the Apple iPone in our life. Becuase its flexible multi touch, very high transmittance, Glass+Glass, anti-scratching, no drifting, IPS full view TFT lcd, high resolution, brightness, high speed and easy flow, supporting animation formats. The color of multitouch HMI is rich and the picture displayed is more delicate. Why many people follows iPhone, just becuase it can bring the users different and beyond imagination experience. Same reasons, why this type panel hmi is very popular in European and American market, just becuase it can bring the project, equipment different experience then to obtain more high value market and to be easily competitive the competitors. Maybe a little try, but to bring a large value, so why not try.
There are lots of temperature control in industry automation. It can select temperature module match the main module plc temperature controller, it also use independent temperature controller to control, both of them are to achieve temperature control. If wanna more flexibility in temperature control, maybe indenpendent temperature module is the first choice. Becuase it can operate without main module plc controller. Mochuan independent plc temperature module integrates an excellent self-tuning algorithm, and user can auto-tune with one button according to needs to accurately obtain PID parameters. Through rs485 communication port, communicate with upper computers of various brands, types of plc, touch screen hmi, configuration software and other upper computers to complete morecomplex logic temperature control.
Selecting HMI screen hardware parameters, mainly look at the CPU running speed and the capacity of the memory. According to the project involves the amount of data exchange animation, the size of the pictures to choose the CPU and memory. When processing more data and picture format is large, needing to choose a fast running speed, memory slightly large HMI. For example, Mochuan 15.6Inch MC-H156E, 7Inch MC-H070CWE, MC-H070CW with 1GHz CortexTM-A7 in CPU. And 10.1Inch MC-H100C, MC-H100CWE with 1GHz cortexTM-A7 and 4GB Flash memory. In addition, also needing to consider the functional requirements needed in the project, such as, how to achieve the multi-level tital pop-up, whether the screen display meets the customer’s need…etc.
