Can not change IP address via Online Device in PLC Next Engineer

Hi Sirs/Madams, I made a project in AXC F 1152 (PLC Next Enginner / Node-Red / Linux code) with a 8 GB MEMORY CARD and it run successfully. When I take the 8 GB MEMORY CARD to the AXC F 2152 and change the program in PLC Next Enginner, it still run as normal. However I have a problem when using AXC F 2152 that when I want to change the IP address in the Online Device tab, it always detect that the PLC type is AXC F1152 (hardware is 2152), so that I can not write the new setting to PLC (if I choose the right IP address, I can connect as usual and write project normally). Could you please show me the way to fix this issue? Thank you so much! -------Viet-------

Hello Viet,

thank you for informing us.
We will look into this issue.

As the AXCF2152 and AXCF 1152 differ quite a lot, you would be saver to reset the SD after switiching hardware. (factory reset)
have a look at this FAQ how to backup all SD Contents.
https://www.plcnext-community.net/en/component/fss/?view=faq&catid;=8&faqid;=112
BUT! Check the upperdir for modifications you actually want to keep.
And only restore those afte SD was reinitialised.
like the nodered installation ect… We can not guarantee that the PLC works fine in this state use and test with caution!
A reset is highly recommended!

If the IP address is the only issue you have right now.
you could modify this in the “/etc/network/interfaces” file.

kind regards,
Oliver

Hi Oliver, Thank you so much for your kind feedback! I already try to back up and copy the project (upperdir folder) to the new SD card, and the AXC F 2152 can run normally, however when I search in online device, it always detect that it is AXC F1152 type (if you use the 1152 project, you can easily change the IP address of 2152 PLC in this case) :(. I think that the most safe way now is remake a same project in 2152 from the beginning to ensure the stable operation. Thank you so much again! --------Viet-----------

Hello Viet,

thats exactly where you have to be cautious.
Do not backup the whole Upperdir but only the files that you actually need and where you know that they are save to use with the changed Hardware.

For example the “upperdir/etc/plcnext” folder should not be touched as there are some HW specific configuration files stored.

Reseting and setting it up from fresh is surely the savest approach.

kind regards,
Oliver
