Default setting 34: Dual Slave mode with setpoint via AS-i field bus
The control accesses the two slaves of the converter each via four bits.
Via slave 2, in accordance with profile 7.A.E, the control specifies the commands listed below (AS-
i.DO0 … AS-i.DO2).
Via slave 1, the control sends the command for quick stop and the data in cyclical or acyclical
mode.
The control requires one bit per slave in order to specify the slave.
Default setting 34, slave 2 with profile 7.A.E: Control -> converter
• AS-i.DO0 -> ON / OFF 1
• AS-i.DO1 -> OFF 2
• AS-i.DO2 -> Acknowledge fault
• AS-i.DO3 -> Select slave A or slave B, interconnected internally
If the control specifies the speed setpoint, the converter replies:
Default setting 34, slave 2 with profile 7.A.E: Converter -> control
• p2080[0] = 53.13 PLC ready to switch on -> AS-i.DI0
• p2080[1] = 899.11 Pulses enabled -> AS-i.DI1
• p2080[2] = 722.0 State DI0 -> AS-i.DI2
• p2080[3] = 722.1 State DI1 -> AS-i.DI3
If the control sends a diagnostic request via AS-i.P0, the converter replies with the currently
pending fault or alarm messages.

Default setting 34, slave 1 with profile 7.A.5: Control -> converter
• AS-i.DO0 -> Time signal for the CTT2 transfer from the AS-i master
• AS-i.DO1 -> Data bit for the CTT2 transfer, four bytes cyclically or acyclically via PIV.
The reading and writing of parameters is possible via the PIV. Because
data is transferred bit-by-bit, the read and write process is very slow.
• AS-i.DO2 -> p0881 = 2093.4 Override quick stop
• AS-i.DO3 -> Select slave A or slave B, interconnected internally
Default setting 34, slave 1 with profile 7.A.5: Converter -> control
• p2080[4] = 722.2 State DI2 -> AS-i.DI0
• p2080[5] = 722.3 State DI3 -> AS-i.DI1
• Serial data transfer CTT2, four bytes cyclically or acyclically via PIV. The
reading and writing of parameters is possible via the PIV. Because data
is transferred bit-by-bit, the read and write process is very slow.
