5.1 Read ID string
(read from slave)
Via the AS interface module, specific data from the frequency inverter can be read out by means of the Read
ID string
command. The information and values in the ID string will first be shown when the AS interface has
recognised the frequency inverter.

5.2 Read diagnosis string
(read from slave)
By means of the Read diagnosis string command, the process and status data of the frequency inverter can be
read out and analysed via the AS interface. The information and values in the diagnosis string will first be
shown when the AS interface has recognised the frequency inverter.
