Top hmi touch screen panel provider: Human-Computer Interaction (HCI): The science of designing, evaluating, and implementing interactive computing systems for use by people and the study of these phenomena. HCI and human-computer interface are two concepts that are closely related but not identical. The RelationShip Between Human Computer Interaction and HMI: Human-computer interaction is the interaction between a human and a machine, which is essentially the interaction between a human and a computer. Or from a broader perspective: HCI refers to the interaction between a human and a machine containing a computer. Read even more details at https://www.mochuan-drives.com/products-56168.
The selection of PLC should be mainly considered from the PLC model, capacity, I/O module, power module, special function module, communication networking ability and other aspects. The basic principle of PLC model selection is to meet the functional requirements and ensure reliability and convenient maintenance, and strive for the best performance-price ratio. The selection should mainly consider reasonable structural type, installation method selection, corresponding functional requirements, response speed requirements, system reliability requirements, model as much as possible unified and other factors.
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.
There is no a good way that a conventional resistive screen can be implemented, becuase its only support the operation temperature from 0°C to 50°C, it is far enough to meet. But Mochuan have another series type HMI panel, wide-temperature metal shell resistive hmi panel, supporting the operation temperature from -20°C to +70°C, it is very helpful to require higher or lower operation temperature working environment, such as Canada, Russia and America …etc, when winter is coming the temperature is very low. So this type metal shell hmi panel is the best choice. So it requires a good positioning, what type of HMI screen to select. For example, used in the renovation of equipment, used in the new development of equipment, the target market is high-end or low-end, whether the customer has special requirements, or to achieve a certain expected results, these factors should be taken into account, and then to make a correct choice is very necessary.
Supporting customized special technical parameters, special application scenarios or special process, special function realization, special performance, special application including shape, color etc. With NO MOQ before mass production. And will not accept to quantity production before customer 100% confirmation its stable quality to run in the device or equipment. Becuase quality is the soul of an enterprise. MochuanDrives customized pmsm motor mainly focuses on high-tech , high-end development, design, production, sales. Find even more details at mochuan-drives.com.
Why touch panel interface always fail to communicate with PLC? Common reasons why touchscreens do not communicate with PLCs 1. whether the correct communication protocol is selected (Modbus, Profibus, CANopen, etherCAT) 2. Is the communication line normal (RS232 rxd TXD GND RS485 a+B-CANopen CAN_L CAN_H CAN_GND ether cat network cable) 3. Whether the communication parameters are correct (station number, baud rate, parity bits) 4. Whether there is interference The program determines that the communication between HMI operator interface and plc has fialed
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.
Choosing the right industrial hmi touch screen panel and plc can not only adapt to the electrical room’s multi-interference operation environment, but also enable each cabinet to achieve intelligent operation management, intelligent maintenance safety, intelligent new energy generation, etc., in order to achieve the goal of enhancing the electrical room’s core competitive advantage and promoting the sustainable development of electricity.
