Siemens SINAMICS G110M - Control Via AS-I; Single Slave Mode

8.7 Control via AS-i
8.7.1 Single slave mode
In Single Slave mode, four bits are available for the communication between the AS-i master and
the converter. The four 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 available; both work with pro󹪝le 7.F.E.
• Default setting 30: Standard Single Slave mode
• Default setting 32: Modi󹪝ed Single Slave mode
Default setting 30: Standard Single Slave mode
In standard addressing, the control speci󹪝es the speed setpoint via the motor control bits (AS-
i.DO0 … AS-i.DO3).
Control -> converter
• AS-i.DO0 -> p1020 = 2093.0 Fixed speed bit 0
• AS-i.DO1 -> p1021 = 2093.1 Fixed speed bit 1
• AS-i.DO2 -> p1022 = 2093.2 Fixed speed bit 2
• AS-i.DO3 -> p1023 = 2093.3 Fixed speed bit 3

Converter -> control
If the control speci󹪝es the speed setpoint, the converter replies:
• p2080[0] = 53.13 -> AS-i.DI0 Operational enable for PLC
• p2080[1] = 899.11 -> AS-i.DI1 Pulses enabled
• p2080[2] = 722.0 -> AS-i.DI2 State DI0
• p2080[3] = 722.1 -> AS-i.DI3 State DI1
If the control sends a diagnostic request via AS-i.P0, the converter replies with the currently
pending fault or alarm messages.
