In WinCC I have backtraced to alarm to be DB1001.DBW44 Bit 3 but which bit in that double word is bit 3? Attachment Counter.zip (339 Downloads)

Remember that bit can be writed in many different ways, in some cases losing the possibility to find it with the cross reference. I hope you are sure? So is this the way it works - the 2 words are switched around? DB1001.DBW44 Bit 0 = DB1001.DBX45.0 DB1001.DBW44 Bit 1 = DB1001.DBX45.1 DB1001.DBW44 Bit 2 = DB1001.DBX45.2 DB1001.DBW44 Bit 3 = DB1001.DBX45.3 DB1001.DBW44 Bit 4 = DB1001.DBX45.4 DB1001.DBW44 Bit 5 = DB1001.DBX45.5 DB1001.DBW44 Bit 6 = DB1001.DBX45.6 DB1001.DBW44 Bit 7 = DB1001.DBX45.7 DB1001.DBW44 Bit 8 = DB1001.DBX44.0 DB1001.DBW44 Bit 9 = DB1001.DBX44.1 DB1001.DBW44 Bit 10 = DB1001.DBX44.2 DB1001.DBW44 Bit 11 = DB1001.DBX44.3 DB1001.DBW44 Bit 12 = DB1001.DBX44.4 DB1001.DBW44 Bit 13 = DB1001.DBX44.5 DB1001.DBW44 Bit 14 = DB1001.DBX44.6 DB1001.DBW44 Bit 15 = DB1001.DBX44.7
