3.5 Enquiry as ranges with address

Low resolution

This telegram reads in a range of DCS values. The number is transmitted with the enquiry. In
addition to the one described in chapter "3.3 Enquiry as block with address“ an address from
0 to 9 is transferred, so that several VEGASCAN 850 can be operated on one BUS system
(e.g. via a RS 485 interface).
