FX3U with GX Works2 or GX Developer - no ip change possible

[pjw 0]

Hi,

I appreciate any help to understand how to change ip in my FX3U mitshubishi plc.

I can connect to it via default address but can't change it.

If I try to do it by GX Works2 to i get info that "Connected PLC is attempting to write an unsupported data. Please check the PLC version". I mean when I try to set in project window by

Parameter>>PLC Parameter>>Ethernet Port
(i can fill this window and save it in program, but when I try to write it to plc, then get message above)

 

But in GX Developer i even can't set anything as this window for network parameters is missing.

Paramter>>PLC Parameter

(there is no window for network settings)
