Hmi supplier right now: Multi-touch capacitive hmi panel is new design and very popular with the market. Why? It is similar the Apple iPone in our life. Becuase its flexible multi touch, very high transmittance, Glass+Glass, anti-scratching, no drifting, IPS full view TFT lcd, high resolution, brightness, high speed and easy flow, supporting animation formats. The color of multitouch HMI is rich and the picture displayed is more delicate. Why many people follows iPhone, just becuase it can bring the users different and beyond imagination experience. Same reasons, why this type panel hmi is very popular in European and American market, just becuase it can bring the project, equipment different experience then to obtain more high value market and to be easily competitive the competitors. Maybe a little try, but to bring a large value, so why not try. Find even more info at human machine interface manufacturer.
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.
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.
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 additional information 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.
