Siemens SINAMICS G110M - Dual Slave Mode

Control -> converter
• AS-i.DO0 -> p3330.0 = 2093.0 ON clockwise / OFF 1
• AS-i.DO1 -> p3331.0 = 2093.1 ON counter-clockwise / OFF 1
• AS-i.DO2 -> p0810 = 2093.2 Speed via potentiometer or AI0
• AS-i.DO3 -> p2104 = 2093.3
p0852 = 2093.3
Acknowledge errors with a positive edge
Operating enable, if p2093.3 = 1
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 speci󹪝ed via AS-i.P0 … AS-i.P3. A diagnostic request is also performed when
AS-i.P0 is sent.
This means, if the control speci󹪝es 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.
• AS-i.P0 Scaling factor bit 0
• AS-i.P1 Scaling factor bit 1
• AS-i.P2 Scaling factor bit 2
• AS-i.P3 Scaling factor bit 3

8.7.2 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 󹪝xed setpoints
• Default setting 34: Dual Slave mode with setpoint via AS-i 󹪝eld bus
