Parameter data transfer
Parameter data are transmitted via the fieldbus as so-called SDOs (Service Data Objects).
The SDO services provide for the write and read access to the object directory.
The SDO channel provides for the access to
and Lenze
codes by means of the CoE protocol.
In general, the parameter data transfer is not time-critical.
Parameter data are, for instance, operating parameters, motor data, diagnostic
information.
9.1
Establishing a connection between master and slave
Basically a master can always request parameter jobs from a slave if the slave is at least in
the "Pre-operational" state.
