Converter -> control
The converter sends as response:
• p2080[0] = 899.0 -> AS-i.DI0
Ready for switching on
• p2080[1] = 807.0 -> AS-i.DI1
Control priority
• p2080[2] = 722.0 -> AS-i.DI2
State DI0
• p2080[3] = 722.1 -> AS-i.DI3
State DI1
If an alarm or fault is pending in the converter, it sends a warning or fault message.

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
converter, 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.

Dual slave mode
In Dual Slave mode, eight bits are available for the communication between the AS-i master and
the converter. The eight bits are used to transfer process data. In parallel, the control can start
a diagnostic request via AS-i.P0.
The following default settings are possible:
• Default setting 31: Dual Slave mode with fixed setpoints
• Default setting 34: Dual Slave mode with setpoint via AS-i field bus
