Fig. 5-21 Example: Writing parameters via PROFIBUS
Note
The ”FC 93” SIMATIC S7 block can be used to ”write parameters via
PROFIBUS”.
This block is included in the toolbox of the CD for ”SIMODRIVE 611
universal” in the file ”s7_Baust.arj” and is documented using its block
comments.
There are additional application examples in the toolbox with the
”read/write parameter” function
(e.g. interface 611u <––> S7 in the file ”611u39.arj”).
