Hello everybody.
I have a network of 5 head flex adapter,3 of them had their "Profibus" led off; I've replaced one of them with a new one; after a few moment the other two entered their normal Staus; ie the "STATUS" and "PROFIBUS" LEDS on; but the "PROFIBUS" led on the newly changed adapter is always off.
I take another new one and replace it but the default remains.
I turn back the former adapter which had it's "PROFIBUS" led off and all is fine.
I'm a bit confused and I really dont find any logical reason fo this phenomena.
Please can someone explain me.
Best regards
