Reading accounting data 20H
The accounting data are interrogated by means of an SD3 inter-
rogation to basic address 20H. The data of a measuring channel
are transmitted in blocks with a message. It is not possible to
access individual parameters of the accounting function. The
offset which is sent in the interrogation determines the number
of the measuring channel whose data are to be read. The byte
number is to be entered into the interrogation in accordance with
the data field size.
