• 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.
• Time signal for the CTT2 transfer to the AS-i master
Macro 34: AS-i Dual Slave with fieldbus setpoint
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.

• AS-i.DO0
• AS-i.DO1
• AS-i.DO2
• AS-i.DO3
If the control specifies the speed setpoint, the converter replies:
Macro 34, Slave 2 with profile 7.A.E: Converter → control
• p2080[0] = 53.13 PLC ready to switch on
• p2080[1] = 899.11 Pulses enabled
• p2080[2] = 722.0 State DI0
• p2080[3] = 722.1 State DI1
If the control sends a diagnostic request via AS-i.P0, the converter replies with the currently
pending fault or alarm messages.
