Plc controller manufacturer and supplier today
High quality hmi touch screen factory: 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.

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.
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.
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 more info on 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.
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.
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.
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.
In the wisdom of industry, electrical cabinet control equipment is suitable for electric facilities, chemical plants, mechanical plants, plant electrical control, network companies electrical control, site large electrical equipment control, etc., to provide convenient electrical management services for the majority of enterprises. Whether it is a small or large electrical cabinet control equipment, it can easily manage the whole company, the whole enterprise, the whole factory electrical equipment.
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.
