Change the signal interconnection of the telegram
If you want to change the signal interconnection or extend telegrams, you have to do the
following:
Table 6- 17 Procedure
Parameter
Description
p0922 = 999 PROFIdrive telegram selection
999: Free telegram configuration with BICO
p2079 = 999 PROFIdrive PZD telegram selection extended
999: Free telegram configuration with BICO
Now you can freely interconnect all signals of the fieldbus interface.
For further information refer to the function block diagrams 2468 and 2470 of the List
Manual.
6.2.1.12
Slave-to-slave communication
"Direct data exchange" is sometimes called "slave-to-slave communication" or "data
exchange broadcast". Here, slaves exchange data without any direct involvement of the
master.
You can find more information in: "Manuals for your inverter in the fieldbus function manual
(Page 387)".
6.2.2
Acyclically reading and writing inverter parameters
The inverter supports the writing and reading of parameters via acyclic communication:
●
For PROFIBUS: Up to 240 bytes per write or read request via data set 47
●
For PROFINET: Write or read requests via B02E hex and B02F hex
You will find more information on acyclic communication in the Fieldbus Function Manual;
see also section: Manuals for your inverter (Page 387).
