Example
● AO 0 should display the value written with object ANALOG OUTPUT 0 via the control. In
this particular case, no other settings are required in the inverter.
● AO 1 should display the smoothed current actual value. To do this, you must set
p0771[1] = 27 (r0027 smoothed current actual value).
In this case, a write access via the object ANALOG OUTPUT 1 to p0971[1] results in a
fault message in the control
Note
Reset to the factory setting for BACnet
If you set communication via BACnet (p2030
= 5), when restoring the factory settings, the
analog outputs are again interconne
cted with p0771[0] = 791[0] and p0771[1] = 791[1].

BIBBs used by the inverter
The BIBBs (BIBB:

lock) are a collection of one or several
BACnet services. BACnet services are subdivided into A and B devices. An A device
operates as client and a B device as server.
The inverter is a server and therefore operates as B device, as "BACnet Application Specific
Controller" (B-ASC).
It uses the following executed BIBBs.
