VB12001000 = Type of variable (R Parameter)VW12001002 = NC Variable Index (R Parameter Index +1)VB12000000.0 = Start Signal MUST be reset after transferVB12000000.1 = Read (0) Write (1) VB12002000.0 = Request complete (Could be used to reset start signal)VD12003004 = Variable value (When read from NC)VB12000001 = Number of data sets to be transferedVB12003000.0 = Variable is ValidVD12001008 = Variable value (When Written to NC) Regards SteveJ
