hi,

i have an EM-277 which was communicating fine as slave with s7-300 2PN/DP via profibus.

now i've put an IE/PB link between the which i wish to communicate via IE with s7-300 and via PB as slave and master. however, i have an SF lit on continuously and BF2 blinking.

attached are diagnostic screen shots.

any useful suggestion please.

thanks
