•
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.

Default setting 34: Dual Slave mode with setpoint via AS-i field bus
The control accesses the two slaves of the inverter 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.
