6.2 How to configure the host (master)
For communication with the inverter, the host (master) must be configured first.
Defining the user data length
• The AS-Interface Communication Unit supports the configuration of max. 8 process data words
(max. 64 bytes).
• The user data length is defined during the initialisation phase of the master.
• The user data lengths for process input data and process output data are identical.

Note!
Observe the direction of the information flow.
• Process input data (Rx data):
Process data from the inverter (slave) to the host (master)
• Process output data (Tx data):
Process data from the host (master) to the inverter (slave)
