selected, the data elements parameter number and
parameter value must be interpreted differently. For single-digit hexadecimal parameter no. the
following interpretations must be observed:
In the standard ASC-I1 protocol mode the data
element „Parameter Value“ with decimal values
(00-99) has to be used. The values for the data item
„Parameter No.“ are hexadecimal values
(0-F).
Only in ASC-W1 mode (
) the data
elements „Parameter No.“ and
„Parameter Value“ have to be used as hexadecimal values (0-F or 00-FF).
For two-digit hexadecimal parameter numbers (Parameter No.), the
parameter value must always be sent in two digits hexadecimal.
