Configuring the fieldbus
7.3 PROFIdrive profile for PROFIBUS and PROFINET
Inverter with CU230P-2 Control Units
130 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
To configure direct data exchange, proceed as follows:
1. In the control, define:
– Which inverters operate as publisher (sender) or subscriber (receiver)?
– Which data or data areas do you use for direct data exchange?
2. In the inverter, define:
How does the subscriber process the data transferred using direct data exchange?
You have configured direct data exchange.
See also Section: Configuring slave-to-slave communication in STEP 7 (Page 444).
You can communicate with the inverter both cyclically and acyclically via PROFIBUS and
PROFINET.
The inverter supports the following types of acyclic communication:
● Reading and writing parameters via "data set 47" (up to 240 bytes per write or read
request)
● Reading-out profile-specific parameters
You can find a STEP 7 program example for acyclic data transfer in Section STEP 7
program example for acyclic communication (Page 440).
