Plc controller wholesale manufacturer by mochuan-drives.com: 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 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.
Consistency principle: Including the consistency of color, operation area consistency, text consistency. That is, on the one hand, the interface color, shape and font are consistent with national, international or industry common standards. On the other hand, the interface color, shape and font are self-contained, and the color of different devices and their same design state should be consistent. Consistency in the aesthetic design of the interface details makes the operator feel comfortable when looking at the interface, so as not to distract his attention. Consistency also reduces errors for new operators, or for operators dealing with problems in emergency situations.
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? See extra info on https://www.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).
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.
