2.6 Transmitting parameter data
With Lenze devices ”codes” are parameter data.
• Parameter data are, for instance, set when the plant settings are made during commissioning
or when the material for the production machine is changed.
• Parameter data are transmitted as so-called SDOs ( Service Data Objects ) via the system bus
and acknowledged by the recipient, i.e. the transmitter receives a message whether the
transmission was successful.
