NB Designer giving "data reading error" on download

3 posts in this topic

I have a NB7W HMI connected to a CPIH over RS232. I'm connected to the HMI over USB and when I try to download my project, it starts the downloading GUI process and fails at a random time and shows a popup that says "data reading error". The HMI is locked up at this point and needs to be restarted. This is a fresh HMI and has not previously had a program on it. I created a blank project to make sure I didn't do anything weird in my program, but got the same result when I tried to download. Has anyone experienced something like this before? Its made it as far as 50%, and has also failed almost immediately.

 

Thanks in advance.

I have the same problem, apparently the cause of the power supply HMI is less than 24V, after the voltage I increase the download is successful

I would  have never (well maybe not never) thought of that. :clap:
