Plc controller wholesale provider today: The human-machine interface is the central link in the human-machine system, mainly by the safety engineering sub-discipline safety ergonomics to study and propose solutions based on the safety engineering equipment engineering, safety management engineering and safety systems engineering to study specific solutions and measures safety ergonomics. It realizes the conversion between the internal form of information and the acceptable form for human beings. Discover extra information at hmi suppliers.
Response Speed Requirements: PLC is a general controller designed for industrial automation, and the response speed of different grades of PLC can generally meet the needs of its application range. If you wanna use plc across the range, or some functions or signals have special speed requirements, you should carefully consider the response speed of the plc, you can choose a plc with high-speed i/o processing function, or choose a plc with a fast response module and an interrupt input module.
Interaction design is subordinate to the product system and is a strong support and refinement to successful product design. If we use the system theory point of view, interaction design is a subsystem of the product design system. Design Principles: The following principles should be considered for the design of human machine interface. The basic user-centered design principle: In the design process of the system, designers should grasp the characteristics of users and discover the needs of users. Users’ opinions should be constantly sought and consulted throughout the development process of the system. The design decisions of the system should be integrated with the users’ work and application environment, and the users’ requirements for the system must be understood. The best way is to involve real users in the development, so that developers can properly understand the needs and goals of users, and the system will be more successful.
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.
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? Discover extra information 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).
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.
Electrical cabinets are integrated cabinets used to accommodate electrical or various electrical equipment used as a carrier for electrical control equipment. It can provide strong protection against water, dust and electromagnetic interference to the stored objects. In the era of big data and the construction of intelligent industry, electrical cabinet control equipment is also playing a very important role. How can we better control the electrical equipment in the harsh environment of the electrical room? Here we recommend Mochuan drives industrial hmi touch panel for embedded installation.
