As-I Profile - Siemens SINAMICS G110D Operating Instructions Manual

● Enter configuration data of the specific AS-i slave.
● Specify the I/O configuration.
● Set the AS-i parameters.
The AS-i standard slave can only be placed at an AS-i address in the A area. This address is
then no longer available in the B area.
As an option, at start-up parameters can be permitted - whether this parameter can be used
depends on the slave type.
If the AS-i slave does not support the ID1/ID2 codes, the values F (hex) must be entered.

AS-i Profile

AS-i Standard
The Inverter uses the extended AS-i specification V3.0, specifically to allow serial
communications over the AS-i bus. The specific profile used by the Inverter is S-7.A.5 which
allows 50 bps bi-directional communications for 2 digital inputs and 2 digital outpus.
The Inverter appears as two logical slaves on the AS-i bus, although the slaves are actually
contained within the same unit.
The first slave (Slave 1), utilizes the combined transaction type 2 (CTT2) protocol to allow
both cyclic and acyclic transter of parameter data to and from the master as well as digital
process data.
The second slave (Slave 2) transfers further process data and allows access to basic
diagnostic information through the reply to a parameter request.
The details of the individual slave identities are given in the table below:
