Function block FB283
Overview
The function block FB283 is an interface block that connects an inverter with basic positioner
to a SIMATIC S7 controller via PROFIBUS/PROFINET.
The block FB283 transfers all of the required process data to and from the drive. It is suitable
for both controlling the basic positioner and for a pure speed-controlled drive.
The FB283 additionally provides the following functions:
●
Reading and writing parameters in the inverter.
●
Reading out the fault buffer of the inverter.
●
Transferring up to 16 traversing blocks when a function is initiated.
●
Reading or writing a maximum of any 10 parameters with one job, e.g. for product
adaptation.
A configuration example and a description of the FB283 can be found on the Internet: FB283

Extend telegrams and change signal interconnection
Following selection of a telegram, the inverter interconnects the corresponding signals with
the fieldbus interface. The inverter protects this interconnection against changes.
Extend telegram
If you want to extend a telegram, you have to do the following:
Table 6- 16 Procedure

p2079
PROFIdrive PZD telegram selection extended
Set the suitable telegram:
7:
9:
110:
111:
Standard telegram 7, PZD-2/2
Standard telegram 9, PZD-10/5
SIEMENS telegram 110, PZD-12/7
SIEMENS telegram 111, PZD-12/12
Now you can extend the telegram by interconnecting the PZD send words and PZD receive words
with signals of your choice.
For further information refer to the function block diagrams 2468 and 2470 of the List
Manual.
