ctrlx Drive in Profinet issue

Hello,

we've a customer who has some ctrlx Drives under a SIEMENS PLC on Profinet,

they noticed they loose communication up to 2 times per day.

when they have the communication interruption, the drive appear in "Rescue System" mode, with the default IP adress : 192.168.0.1, which create Duplicte IP Address in the network.).

do you any idea about that ?

attached the par file of 2 drives (1 with OP810 with issue and another OP741 without any problem).

thanks.
