Quality hmi touch screen panel manufacturer and supplier: Specifically, the two-way communication between the HCI user and the machine containing the computer, in a certain symbol and actions to achieve, such as hitting keys, moving the mouse, displaying symbols/graphics on the screen, etc. This process includes several sub-processes: identifying the interactive object – understanding the interactive object – grasping the object situation – information adaptation and feedback, etc.; and the human-machine interface is the communication media or means between the user and the machine system containing the computer, which is the software and hardware supporting the two-way information interaction between human and machine. Here the interface is defined as the media or means of communication, and its physical embodiment is the relevant supporting software and hardware, such as a graphic display terminal with a mouse, etc. See even more details on hmi touch screen panel.
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.
Interaction design is subordinate to the product system and is a strong support and refinement to successful product design. If we use the system theory point of view, interaction design is a subsystem of the product design system. Design Principles: The following principles should be considered for the design of human machine interface. The basic user-centered design principle: In the design process of the system, designers should grasp the characteristics of users and discover the needs of users. Users’ opinions should be constantly sought and consulted throughout the development process of the system. The design decisions of the system should be integrated with the users’ work and application environment, and the users’ requirements for the system must be understood. The best way is to involve real users in the development, so that developers can properly understand the needs and goals of users, and the system will be more successful.
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.
The Fifth Step: Selecting A Supplier The correct undertanding of a supplier is to be able to provide very stable performance products and after sale and technical service, can do online one-to-one timely guidance and solution. In the face of unforeseen events have the feasibility and flexibility of the program to provide. After all, industrial HMI PLC is a technical product, needing for a manufacturer’s cooperation and support, to make customer worry-free. Maybe you can choose Mochuan Drives. A small try will bring a high value, so why not try?
Less performance used to match a very high cost, so will it worth? And where is your market point? Maybe more consider another China brand with a very perfect performance too, such as Mochuan brand. Welcome contact us to discuss more. The Second Step: Selecting The HMI Screen Size There are two means of size here. One is screen display screen size, the other is CPU size. Integrating the scale of the entire project, to determine the size of the HMI panel needs, through the project as a whole to present the effect. Do not select the size is too small or too large, becuase too small is look very compact and not enough to operate in well, too large will look the overall proportion of the untuned and waste. It requires engineers to design a good enginnering diagram in advance to allocate the size of each accessory part of the proportion. Wanna win every high value market, it needs to pre-design and seriously selected, but not take for granted. See additional information on mochuan-drives.com.
Touch panel interface and PLC communication fail communication, needing check four factors: 1. Are the PLC parameters consistent with those in the project? 2. Are the communication lines connected according to the pins in the wiring diagram. 3. Is the COM port set in the project correct when connecting on the screen. 4. If it is confirmed that the parameters and wiring are OK, see whether it is the PLC program or the PLC address.
This type touchscreen panel support 7inch, 9.7inch, 17inch, 22inch and 32inch, is enough to select suitable model for the project from application and cost. There are two operating temperature -10°C to 60°C and -20°C to 70°C. And all the size and model is to support ethernet, 2pcs rs485 or 2pcs rs232 is in optional. Adpoting industrial grade high quality components, high protection level design, comprehensive three-proof coating, no matter the wet underground mine, high temperature gobi or corrosive gas, oil mist or dust factory environment, can easily cope with, easy to handle.
The plastic enconomic resistive HMI panel is very high advantage competitive series. There are multiple parameter, resolution, serial port to select for user to achieve real matching per project budget for one size. But it does not mean, this type HMI touch panel performance, resolution…etc is not in perfect but more flexible. For example, there are 800×480, 1024×600 resolution, ethernet, 2xRS485, 2xRS232, RS422 are in optional for 7inch touchscreen HMI.
Electrical cabinets are integrated cabinets used to accommodate electrical or various electrical equipment used as a carrier for electrical control equipment. It can provide strong protection against water, dust and electromagnetic interference to the stored objects. In the era of big data and the construction of intelligent industry, electrical cabinet control equipment is also playing a very important role. How can we better control the electrical equipment in the harsh environment of the electrical room? Here we recommend Mochuan drives industrial hmi touch panel for embedded installation.
