Question

Hi!

I am facing issues with the Modbus TCP Slave functionality of a RUT240 in combination with Kepware Kepserver. I am successfully able to read the Modbus data from the RUT240, however writing data does not work (more specifically, the reboot function does not work for me). Do you have any idea, why this is not working as expected? See also attached screenshots!

Latest firmware (00.07.04.2) is installed. If this is helpful, I can also provide a Kepserver configuration file.

Thanks!

David

Hello,

I was able to reboot the device by setting register 207 to 1. Although, it took ~5-10 seconds for the device to start rebooting.

Could you try setting register 206 and/or 207 to 1? (400206 / 400207)

If it fails,  could you check if you can do it from the router itself using Modbus Master functionality?

Kind Regards,
