If the control sends a diagnostic request via AS-i.P0, the inverter replies with the currently
pending fault or alarm messages.
For details, see AS-i System Interface Manual
(https://support.industry.siemens.com/cs/gb/en/view/1171856).
Default setting 32: Modified Single Slave mode
In Single Slave mode with modified addressing the control specifies the following:
AS-i.DO0
>
AS-i.DO1
>
-clockwise / OFF 1
AS-i.DO2
>
Speed via potentiometer or AI0
AS-i.DO3
>
= 2093.3
= 2093.3
Acknowledge errors with a positive edge
Operating enable, if p2093.3
= 1
The inverter sends as response:
p2080[0] = 899.0
>
-i.DI0
p2080[1] = 807.0
>
-i.DI1
p2080[2] = 722.0
>
-i.DI2
p2080[3] = 722.1

-i.DI3
If an alarm or fault is pending in the inverter, it sends a warning or fault message. For details,
see AS-i System Interface Manual
(https://support.industry.siemens.com/cs/gb/en/view/1171856).
Scaling factors for the speed
The scaling factor is specified via AS-i.P0 … AS-i.P3. A diagnostic request is also performed
when AS-i.P0 is sent.
This means, if the control specifies a scaling factor and an alarm or fault is pending in the
inverter, it sends the current alarm or fault messages and accepts simultaneously the sent
value consisting of AS-i.P0 … AS-i.P3 as new scaling factor.
AS-i.P0
AS-i.P1
AS-i.P2
AS-i.P3
For details about the scaling factors, see AS-i System Interface Manual
(https://support.industry.siemens.com/cs/gb/en/view/1171856).
