Dual Slave Mode - Siemens SINAMICS G115D Operating Instructions Manual

Converter → control
The converter sends as response:
• p2080[0] = 899.0 →
• p2080[1] = 807.0 →
• p2080[2] = 722.0 →
• p2080[3] = 722.1 →
If the control sends a diagnostic request via AS-i DI0, the converter replies with the currently
pending fault or alarm messages.
• AS-i DI0 = 1, pending alarm messages are replied.
• AS-i DI0 = 0, pending fault messages are replied.
(Page 178)
Scaling factors for the speed
The scaling factor is specified via AS-i.P0 ... AS-i.P3.
This means, if the control specifies a scaling factor, it 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

Manual.

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 interface settings are possible:
• Macro 31: AS-i Dual Slave with fixed setpoint
• Macro 34: AS-i Dual Slave with fieldbus setpoint
