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.
Example: An inverter uses the actual speed value of another inverter as its speed setpoint.
Definitions
● Publisher: Slave, which sends data for direct data exchange.
● Subscriber: Slave, which receives the data for direct data exchange from the publisher.
● Links and access points define the data that is used for direct data exchange.
Restrictions
● Direct data exchange in the current firmware version is only possible for inverters with
PROFIBUS communication.
● A maximum of 12 PZDs are permissible for each drive.
● A maximum of four links are possible from one subscriber to one or several publishers.
Configuring slave-to-slave communication
Procedure
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 now configured slave-to-slave communication.
