Hmi touch screen wholesale provider by Mochuan Drives: 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.

System Reliability Requirements: The reliability of the general system PLC can be met. For systems with high reliability requirements, consider whether to use redundant systems or hot standby systems. PLC should be unified possible. Mainly consider the following three aspects: The model is unified, and its modules can be used as backup for each other, which is convenient for the procurement and management of spare parts. The model is unified and its function and use method are similar, which is conducive to the training of technical forces and the improvement of technical level. The model is unified, its external equipment is universal, resources can be shared, easy to network communication, and it is easy to form a multi-level distributed control system after being equipped with a computer.
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.
In 2022, in order to meet the new needs of customers and the market, our MochuanDrives merged with a professional manufacturer of highly customized servo motors, with more than 20 years of experience in research and development, manufacturing and service of servo motors and brushless motors, especially good at tailor-made high-end motors with special specifications from scratch, until the stable manufacturing of large quantities. With NO MOQ, before large quantities needing to get 100% stable quality confirmation from our customers. Discover additional info at https://www.mochuan-drives.com/.
Specific methods : First, the parameters of the touch screen. Check the parameter settings of the touch screen. Connect the PLC programming software to the PLC test to see what the PLC parameters are and whether the parameters set in the project are the same as those tested. There are several parameters that require special attention: 1. Communication port settings – be sure to confirm that the COM1 port or COM2 port of the PLC connected to the touch screen is clear;2. Device type – this is the most important. If the protocol is not selected correctly, nothing else needs to be said. 3. connection method – the connection between the PLC and the HMI operator interface, confirming whether it is RS485 or RS232C. 4. The touch panel interface parameter is the same as the PLC station number – it must be the same as the setting in the PLC. Next, if the parameters are set to confirm, troubleshoot the wiring.
Multiple color of shell and panel cutout for selecting, it is more flexible to match different project to improve the overall aesthetics and practical. Suggestions and recommendations to our customers through over a decade field experience industry and industry solution through software and hardware, if you work with us. If require the special technology, special function, special size, special parameter, special color, shape or special performance of ihm, welcome contact us for ODM. Mochuan hmi panel manufacturers will be very seriously and give timely feedback.
The regular China lcd human machine interface HMI touch screen is only to support 0°C to 50°C working envornment. HMI panel can not meet the application, the environment require the high or low temperature. It have to find the solution, such as to add one resistance or move the equipment in door or outdoor to make the temperature is suitabe its work needing. But face one question, it is not stable and very inconvenience. To solve this problem, to develop and design new type HMI touch panel, it is metal shell wide-temperature resistive HMI, supporting -20°C to 70°C. This type wide-temperature screen is very popular in Canada, Russia, United States…etc.
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.
MochuanDrives supports industrial hmi touch panel from 4.3inch to 32inch, and supports multiple serial ports with different communication parameters to meet the needs of different projects. Provide free software and online technical one-on-one worry-free after-sales technical support. Through the setting of early warning programming, can monitor in advance whether there is a failure of the equipment in the electrical room, can effectively prevent the loss of sudden damage to equipment.
Human-machine interface refers to the field of human and machine in information exchange and functional contact or mutual influence or interface said human-machine bonding surface, information exchange, functional contact or mutual influence, refers to the hard contact and soft touch of human and machine, this bonding surface includes not only the direct contact of the point line surface, but also the role of space for information transfer and control at a distance.
