7 Parameter data transfer
The PC (client) used for setting parameters and the controller (server) communicate with
one another by exchanging data telegrams via the Ethernet. The parameter data are
contained in the user data area of the data telegram.
 Parameters are set, for instance, when the system is initially adjusted during
commissioning or when the material of the production machine is changed.
 The parameter data are transmitted as SDOs (Service Data Objects) and confirmed by
the receiver, i.e. the transmitter receives a feedback whether the transmission was
successful.
The SDOs provide for the write and read access to the object directory in the controller.
 The transmission of the parameter data usually is not time-critical.
 The parameter data are saved in Lenze devices as "codes".
Via the codes, for instance operating parameters, motor data or diagnostics
information can be set.

Note!
With regard to the writing access on parameter data, observe that the changes
carried out are not stored automatically in the controller.
In order to save changed parameter settings with mains failure protection, carry
out the device command C00002 = "11: Save start parameters".
