Premium hmi touch screen factory: 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. See even more details on switching power supply.
Specifically, the two-way communication between the HCI user and the machine containing the computer, in a certain symbol and actions to achieve, such as hitting keys, moving the mouse, displaying symbols/graphics on the screen, etc. This process includes several sub-processes: identifying the interactive object – understanding the interactive object – grasping the object situation – information adaptation and feedback, etc.; and the human-machine interface is the communication media or means between the user and the machine system containing the computer, which is the software and hardware supporting the two-way information interaction between human and machine. Here the interface is defined as the media or means of communication, and its physical embodiment is the relevant supporting software and hardware, such as a graphic display terminal with a mouse, etc.
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.
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.
HMI is no longer a simple display and control: In the domestic automation industry, some industries that originally did not use HMI have started to use it, which shows that HMI has become an indispensable part of the customer experience. The user interface of HMI can better reflect the status of equipment and processes, and bring customers a more intuitive feeling through visual and touch effects. Future development trend of human-machine interface: Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries, have been developed in China for decades and are relatively mature industries, and in the long run, there is still a demand for upgrading equipment in these industries. In this upgrading process, there will indeed be some small, has been using relatively low-end products manufacturers are eliminated, but there are also many enterprises in the process of equipment renewal, will demand repositioning, to find those who can meet their development plans, to help them improve their own productivity equipment suppliers.
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.
Less performance used to match a very high cost, so will it worth? And where is your market point? Maybe more consider another China brand with a very perfect performance too, such as Mochuan brand. Welcome contact us to discuss more. The Second Step: Selecting The HMI Screen Size There are two means of size here. One is screen display screen size, the other is CPU size. Integrating the scale of the entire project, to determine the size of the HMI panel needs, through the project as a whole to present the effect. Do not select the size is too small or too large, becuase too small is look very compact and not enough to operate in well, too large will look the overall proportion of the untuned and waste. It requires engineers to design a good enginnering diagram in advance to allocate the size of each accessory part of the proportion. Wanna win every high value market, it needs to pre-design and seriously selected, but not take for granted. Find more details at https://www.mochuan-drives.com/.
How To Solve Communication Failure Between HMI Operator Interface And PLC? When communication fails, some customers guess that it may be a problem with the touch screen all-in-one machine or the interface. Online simulation is to bypass the touch screen, use the PLC to connect directly to the computer, use our configuration software, connect the PLC’s own communication cable to the computer, conduct online simulation and see if the project can communicate.
The Macro instructions of HMI Human Machine Interface are based on C language and the system is developed on Linux. There are multi-types of HMI panel, mainly three types, multi touch capacitive hmi panel, plastic shell enconomic resistive hmi touchscreen panel and metal shell wide-temperature resistive touch screen and small home screen to meet different requirement from application scenarios and market needing. There are rich serial port such as rs485, rs232, rs422, ethernet etc to meet the master and slave to use. Mochuan human machine interface manufacturer suppors the size from 4.3inch to 32inch.
The plastic enconomic resistive HMI panel is very high advantage competitive series. There are multiple parameter, resolution, serial port to select for user to achieve real matching per project budget for one size. But it does not mean, this type HMI touch panel performance, resolution…etc is not in perfect but more flexible. For example, there are 800×480, 1024×600 resolution, ethernet, 2xRS485, 2xRS232, RS422 are in optional for 7inch touchscreen HMI.
