Quality human machine interface provider: 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.
Interaction is a description of the relationship/status of human-machine-environment interaction. The interface is a concrete expression of the interaction between human and machine – environment. Interaction is the contextual portrayal to achieve information communication, and interface is the means to achieve interaction. In the interaction design subsystem, interaction is the content/soul, and interface is the form/body; however, in the larger product design system, both interaction and interface are only a means to solve the human-machine relationship, not the ultimate purpose, which is to solve and satisfy human needs.
Industrial grade fully enclosed embedded industrial hmi touch panel can perfectly cope with all kinds of harsh environment, but also can bring more convenient management services: Installation of embedded industrial hmi touch screen panel in the electrical room cabinet is more conducive to intelligent monitoring and management of the equipment in the electrical room. Through the touch screen monitoring display, you can monitor and detect the running temperature, power output, output power and other conditions of the electrical chassis cabinet in real time to ensure the stable and efficient operation of the electrical room.

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.

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.
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.
The Fourth Step: Communication Mode Preference is given to the HMI Panel itself with lower computer drive touch screen. Firstly, this is will be more convenient and simple in the definition of the subsequent project address and conversion, becuase if you choose Modbus compatible devices, it is necessary to convert the HMI touch screen monitoring address according to the rules of the definition of different lower computer(PLC) manufacturer, which not only greatly increase the workload of engineers and also easy to covert the wrong. Secondly, needing to draw up in advance, a communication program for the entire project. Do it need the ethernet to communicate with the upper computer, or need two rs485 to be maste or slave station communication, or through one rs485 and one rs232 communication to achieve.
