Please see page no.186 and explain me what is meaning of this sentence Error on Underlaid bus (irrelevant for ET200M). Waiting for reply, Yogendra G.

Please me what is meaning of this sentence Error on Underlaid bus (irrelevant for ET200M). Hello YogendraG the BF2 LED is only applicable when an "underlying" bus is created by usingthe IM153-2 as either a Y-Link or DP/PA link. It'smeaning isexplained in cahpter 11 of theSIMATIC Bus links DP/PA coupler, active field distributors, DP/PA Link and Y Link manual. I hope this helps
