Thanks.

1: IP conflict: Already checked, but will check again.
2: I use the same type of power source as for my MODbus configuration, and already placed a stronger power supply
3: I'll test this with another cable.

I've tested that the client looses connection, ethernet cable can be the issue.
Also i connected the devices with a RS485 cable direct, and connection stays stable.

As soon as i have tested this, i'll let you know if it is fixed or not.

Thanks so far.
