Also, where should I assign State.Data.New[1] values? Somewhere in the changeover? At the moment I have just put this code in Station.OnUnitOperational: IF ( Module1_MesFu1.OutImm.TypeDataOk ) THEN StateAddOn.ParImm.TypeNoCur[1] := Module1_MesFu1.OutImm.TypeNoCur; StateAddOn.ParImm.TypeVarCur[1] := Module1_MesFu1.OutImm.TypeVarCur; StateAddOn.ParImm.TypeVersionCur[1] := Module1_MesFu1.OutImm.TypeVersion; END_IF ...
