ZDUE-GPRS-PLUS-VI
Each parameter class includes a range that is reserved for possible
expansions. Parameter expansions that are covered by these reserved
ranges do not lead to any incompatibility between different firmware
versions. If the expansion space is not sufficient, a new parameter class
must be created. This likewise does not lead to any incompatibility, because
a command to set/read this new parameter class from an older firmware will
be acknowledged with ERROR. The reserved parameter ranges are filled in
with '0' (0x30) during communication.
In the following the parameters are sorted by classes and shown in the
same way as their notation in parameterisation commands. The respective
factory configuration is highlighted in bold. The specifications Offset, Len
and Values (ASCII) have the following meanings
Contains the relative address of a parameter within the
Offset
parameter class, relative to the class structure.
Len
Reflects the number of ASCII characters that are
necessary to depict the parameter during communication.
For strings only the number of ASCII characters defined
with 'String Length' is significant (decimal-coded); any
string range that is not used must be filled in.
Values (ASCII)
Contains permissible values (ranges) for the individual
parameters during reading (W1 command) and reading by
means of an R3 command.
This class is implemented only for compatibility reasons. In other models it
specifies the changeover times of the clock from summer time to standard
time and from standard time to summer time. However, because the ZDUE-
GPRS-PLUS-VI does not have a real-time clock, the parameter class 54 has
no significance for operation of the ZDUE-GPRS-PLUS-VI. The parameters
of this class are read-only.
This class describes the general operating parameters of the ZDUE-GPRS-
PLUS-VI. It is defined as an open class, i.e. data sets that are longer than
what is defined here are accepted. The non-specified values are ignored in
evaluation by the device. When the parameters are read only the specified
values are output.
