Hi,

I'm new in PLC programming, i come from years of C language.

I' have a simple project with only a PLC S7-1500 and a Switch PN Scalance XB216. I have to enable the I-DEVICE to communicate with another device (not PLC), a Box PC with a Profinet board.

Without the I-DEVICE setting, the project compiles and it is downaloaded fine on PLC and it goes to RUNstate correctly.

When i enable the I-DEVICE setting, it compiles but when it is downaloaded on PLC, the PLC go to ERROR state and i have this error in diagnostic buffer:

event id 16# 02:39D0

The dignostic buffer doesn't show any other informations about this error.

I've try to change the setting of the Ethernet address from "not networked" to PN subnet as i see in I-Device doucumentation, but i have the same problem, and furthermore with this setting i see a double link from PLC to PLC in Network View.

Do you have any idea about this problem?

Thank you
