Industry-sepcific human machine interface may have specific definitions and classifications, such as industrial human machine interface(HMI or simply industrial HMI). Human-Computer Interaction: Human-Computer Interaction, Human-Computer Interaction (HCI, abbreviated HCI, also known as user interface or user interface): is a study of the interaction between a system and its users. Systems can be a variety of machines, or computerized systems and software. The human-computer interaction interface is usually the part that is visible to the user. The user communicates with the system and operates it through the HCI interface. This can be as small as the play button on a radio, or as large as the instrument panel on an airplane, or the control room in a power plant.
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.
Order principle: That is, in accordance with the order of processing events, access to view the order (such as from the whole to a single item, from large to small, from the top to the bottom, etc.) and control processes, such as the design of monitoring management and human-machine dialogue interface and its secondary interface. Functional principle: That is, according to the specific functional requirements of the object application environment and occasions, various subsystem control types, parallel processing requirements of the same interface of different management objects and simultaneous requirements of multiple dialogues, etc., the human-computer interaction interface is designed with multi-level menus, hierarchical prompt messages and multiple dialogues, so that users can easily distinguish and master the usage rules and characteristics of the interactive interface and improve its user friendliness and ease of operation.
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 reason is rs232 is suitable for communication between local devices, and its transmission distance is generally not more than 15m, and rs232 only allows one-ton-one communication. But rs485 transmission distance is from tens of meters up to 2Km, and rs485 interface allows up to 255 slave station to be connected. These are required to be designed by our engineers, with whom to communicate, how many devices to communicate, how to achieve the final function, whether to take into consider the interference problems of the field environment etc. All of the above are considered.

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.
Mochuan hmi suppliers offer free software, NO MOQ, fast shipment, to deal with us your payment and business are in safe. Offering one-to-one technical support online. The most important, our hmi wholesale is compatible with all brands of plc controllers, such as, Mitsubish FX2N, FX3U, FX3SA, FX5U…Siemens S7-200, S7-300, S7-400,…etc, ABB, Acrel, Allen-Bradley(AB), Delta, Fatek, Fuji, LS, Omron, Panasonic etc. To learn, please have a look our software, there is one list to show it.
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.
