Data transfer
The master (e.g. a PLC) and inverter communicate with each other by exchanging data frames via
the fieldbus. The user data area of the data frame either contains network management data,
parameter data, or process data.
Different communication channels are assigned to parameter and process data in the inverter.
Parameters are for instance operating parameters, motor data, or diagnostic information, which are
stored under a code in the Lenze inverters.
Normally, the transfer of parameters is not as time-critical as the transfer of process data.

Access to the inverter codes
Via the communication module, a higher-level master (e.g. a PLC) can change the properties and the
response of each inverter integrated in the network.
In Lenze inverters, parameters to be changed are listed under codes.
Inverter codes are addressed via indexes when accessing the code through the communication
module.
The indexes for Lenze code numbers are between 16576 (0x40C0) and 24575 (0x5FFF).

Index = 24575 - 1 = 24574
Index = 0x5FFF - 0x1 = 0x5FFE
