FAQ
Siemens Mp370 Touch Screen Replacement Experience
In the afternoon of October 3, 2015, I received a phone call from the company's workshop saying that the paste making touch screen was black and could not be operated. Feel the scene, first use a multimeter to measure the power supply 24VDC, and confirm that the voltage of 23.7vdc is within the normal range. It is indeed the fault of the screen film, and the screen needs to be replaced.I arranged the workshop staff to go to the warehouse to find a mp370 screen with the same model but with a newer order number and version number to replace, install, connect, power on and prepare to download the program.I first found the last modified project file. The file version is winccflexible 2008 SP2. My laptop is already winccflexiable2008sp4. Opening the project file normally only prompts that it needs to be upgraded. Back up the old project file, and then select Yes to open the project file normally. Check each page respectively to confirm that it is consistent with the screen of on-site work.According to previous experience, first enter the touch screen control panel, check the s7transfer page setting parameters, select remote control, set the Ethernet IP address and return to the transmission state; Then adjust my notebook IP address to ensure that IP is different from the network segment, and Ping touchscreen IP address to ensure smooth lines.Select the project file, select menu transmission, check overwrite user management, check IP parameters, click download, the software compilation is completed and the download starts. After waiting about 20 seconds, a prompt "unable to connect the device, please check the line or parameter settings" pops up. This pop-up message does need to be checked if there are no previous preparations, but I don't need to check it now because it has been confirmed that the communication is normal and the device cannot be connected. It is estimated that the OS version is too different from the software in the computer.Select the project file, select OS update, and then a page will pop up to display the two connected computers. There is a lightning symbol on the middle connection, which is constantly moving back and forth. The text above indicates that it is "connecting". After a few seconds, it indicates that it is connected. Then the middle connection bulges a small packet and moves back and forth, and the text above indicates that it is "transmitting... *. Img"; At this time, look at the touch screen and start displaying file names one after another, indicating that OS system files are being updated at this time.After waiting for about ten minutes, the touch screen will restart automatically. After restarting, it will automatically enter the transmission page. At this time, the project file should be able to be downloaded. Select the project file, then select menu transmission, repeat the above transmission operation, and the same transmission page of OS update will pop up. Two computers have a connection, and the lightning in the middle will string back and forth for several times, and it will become a small drum bag and start transmitting the project file. After about 10 seconds, the project transmission is completed, and the touch screen will automatically enter the operation page.Click to open the page and find that the page display and operation are basically normal, that is, click the button and enter the text box, not on time, but oblique, indicating that the new screen needs to be corrected, and then start the fantasy journey of correcting the screen.
