9 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 access to Implemented CoE objects

( 79) 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.
