I/O Engineering - Slave to Slave connection can't be saved

[MST]

Hi everybody,

I'm trying to connect EtherCat Slaves via the slave to slave configuration in the I/O-Engineering (V1.20.1). It works e.g. for the connection between SICK Sensors and the SAFE-X configuration:

I can download the configuration as shown in the picture without any problems.

As soon as I add any connection using the KRC4_secondary_EL6695_1001 slave (example in the picture below)...

... and download or save the project, the configuration is deleted (see below).

It is also deleted, when the configuration is made offline without any conecttion to the EtherCat (Cable unplugged). Therefore I don't think it is overwritten by any other participant in the network. Any idea where my problem is? The communication between the Kuka-Slave and the PLC-App works fine and data exchange is possible. Also the ESI-File is the latest from the KUKA downloadcenter.

Thanks for your help and regards 🙂

Could you please provide us the device description files you are using? Especially the KRC4.

Attached, the description files I use in the project.

For your Info, I got the KRC4 file from the KUKA download center:https://kuka.sharefile.eu/share/view/s7ecbfd0b091f477d88bac2c865f09a3d/fof1a212-aa67-4e34-995b-2b03e...
