10 Handling of the objects

10.1
The communication channel (PKW area) has the following structure:
Designation
Inhalt
Byte No.
The data are transmitted in the Motorola format as, for example, supported by the
S7 PLC from Siemens. Thus, the high byte is on the lower byte and the low byte on
the higher byte.

Parameter values (= data) of the type Integer/Unsigned Integer (16 Bit) and Long (32
Bit) can be written and read. The data type is specific in the order identification. In
data set change-over capable parameters (array) the required data set is stated under
Index.

The index is always on the high byte of "Index" (Byte No. 2), with the low
byte always = 0.
Structure of the parameter identification (PKE):
High Byte
15 14 13 12
AK SPM
Order or reply identification (value range 0 ..15)
Toggle bit for spontaneous result processing
Parameter number (value range 1 to 999)
The order and reply identifications are stored in the AK area. If no parameter
processing is to be done, the "no order" kind of function is to be set.
With bit 11 (SPM), the readiness for spontaneous report processing can be
switched on and off (0 = OFF, 1 = ON, in the present application, the spontane-
ous report processing is not support, so SPM is always 0).
The PNU area transmits the number of the parameter to be processed.
An Excel file, which can be requested, exists for the necessary information
on the parameters with regard to the data type and data set change-over
capacity.
