Slave-to-slave communication
"Direct data exchange" is sometimes called "slave-to-slave communication" or "data exchange
broadcast". With direct data exchange, slaves exchange data without any direct involvement
of the master.
Further information about the "Direct data exchange" function is provided in the Fieldbus
function manual.
