What this means is that you use the comms SFB's instead of the FB's in you logic (e.g. SFB14 GET instead of FB14 GET). What "annoyed' me most is the fact thatthe (S7-300 usable) FB14 GET for example contains internally SFB14, SFC20, SFC 51, SFC58 &SCF59 and ALL of theseare meant to be supported by SP3 of PLCSIMV5.4 (i.e. FB14 should work, but it doesn't). I hope this helps
