Hello

I have a repeater (6ES7972-0AB01-...) In MCC 3 ,It connects to two more MCCs.

I configured it in the hardware configuration and put the address and also turned both keys to ON.

but I have both DP2 AN D DP3  led s ON, RED AND YELLOW.

Could you please help me with that?

Split from 6ES7972-0AB01-0XA0 Diagnostic repeater.

Hello Anosh;

Do you mean the LEDs at DP2 and DP3 are flashing? Are there other apparent lEDs?

From the manual for the Diagnostic Repeater you can see the meaning of the LEDs in various states (see chapter 7, Diagnostics) :

Simatic Diagnostic Repeater for Profibus-DP

If the Repeater has switched off segments 2 and 3, we need to know if this is because no nodes appear on those segments or if the connections are to be reviewed.

Please show us a sketch of your network, showing the nodes and terminators that are acte.

Hope this helps,

Daniel Chartier
