Dear DanT, COM 4 is already set and Buadrate is 57600 set. I changed the Buadrate from 57600 to 19200 due to not communicating. Please see the attached pics. V120 display keypad not working. I checked V120 battery successfully battery shows 3VDC. I do not understand How can i declare V120 PLC has been faulty. Please guide me on what can i do?

Dear Respected Sir/Madam, During the routine maintenance, I was taking project backup from PLC Vision120 after completing uploading PLC went to reboot after rebooting PLC did not communicate properly. So we are going to change this PLC due to no easy solution available to the following issues. I have Vision-120 PLC software VisiLogix. I was facing the serious issue that I have mentioned below with pictures; -We upload the Vision-120 PLC program via Visilogic software. The uploading method was successfully done but after the uploading program, we shut down the PLC and our Laptop for Lunch. after that, I powered the PLC ran the Visilogic app and tried to go online but the PLC did not communicate with the Laptop and also showed a dark screen. After several times tried then I decided to Initialize Reset. After struggling PLC communicated with LAPTOP only for initialization reset mode picture is attached. After completing Bootstrap which shows during initial rest time. After completing this process we tried to download the Uploaded program so the other pictures attached further issues found at the time of downloading. Please I am very very disappointed about this PLC. Kindly give me the best solution on how can i redownload the uploaded project BKPUP. Hope you understand after checking the attached pictures what is the actual issue? Best Regards, Hasan Haider. shhz2005@gmail.com.
