When Power off Ewon All setting go back to defaults

Hello all, I hope some of you can help me with my Problem.
I have eWON x005CD and I am testing to connect with a Siemens S7 1200 PLC through Profibus.
I am facing two Problems… the first one is I f I cutoff power eWON settings all go back to defaults even Date and time.
so do I have to change setting every time I recycle power??
my second Problem is I am trying to connect to a siemens PLC through profibus but I cant find a good explanatory on Tia portal
how do I set the connection of ewon for Profibus through Tia portal ???

thanks

Hello,

How long have you had this device, and how long has this issue occurred?

Also, are you powering the device within the parameters for the unit.

The memory looks to be resestting when you power cycle the device. If there is too much power, it may damage the flash memory, causing it to reset the settings.

As for the TIA settings we do not have any documentation for this type of connection, and it may require for you to reach out to TIA for assistance.
