Plc controller wholesale provider in China: 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. See extra information at switching power supply.
Reasonable Structural Type: There are two structural types: main module and extended module. The average price of each I/O point of the integral PLC is cheaper than that of the module type, and the volume is relatively small, which is generally used in the small control system with a fixed system process; The function expansion of module plc is flexible and convenient, and there is a large choice in the number of I/O points, the ratio of input points to output points, the type of I/O modules…etc, and the maintenance is convenient, generally in more complex control systems.
Frequency principle: That is, according to the frequency of dialogue interaction of the management object design the human-machine interface hierarchical order and dialogue window display position of the list, etc., to improve the frequency of monitoring and access to dialogue. Importance principle: That is, in accordance with the importance of management objects in the control system and the global level, the design of the human-machine interface of the main and secondary menus and the location and prominence of the dialogue window, which helps managers to grasp the importance of the control system, the implementation of good control of the sequence of decisions to achieve optimal scheduling and management.
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? Read extra information on mochuan-drives.com.
Use a multimeter to determine the test wiring according to the pins in the wiring diagram. Verify that the RS485 and RS232C wiring is correct, touch screens differ from various PLC wiring. This can be viewed by referring to Maintenance Control (help documentation for PLC and touch screen communication line connections), which is the basic method for normal troubleshooting of communication problems. Next I show you how to bypass the touch screen problem – online simulation. When communication fails, some customers will guess that there may be a problem with the touch panel interface or a problem with the interface. Online simulation means bypassing the touch screen and using the PLC to connect directly to the computer. Using our configuration software, the communication cable from the PLC itself is connected to the computer and an online simulation is carried out to see if the project can communicate. This can be done with a numerical input element or switch to see if the operation before and after closing the simulator and opening the online simulation is still present and if it prompts a direct NC (NC and previous operations not written down are not connected).

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.
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.
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.
