15 1 Depends on the protocol
On the SINAMICS G120 it is possible, using the function local/remote
control, to change between the command data set (CDS) 0 and 1 of the
control word 1 bit 15. This results in a switching of the command data
sets. The command data set 0 is active in local operation and the
command data set 1 for remote operation. Now in both command data
sets the application-specific parameters for the command and target
value sources can be set.
*Note: In PROFIdrive Profile P0810 = 2090:15 must be set manually.

An example
In the remote control operating mode the commands and target values come from a superior
control system to the inverter by means of a PROFIBUS. By switching to local operation, the
command and target value source is switched and operation is now performed locally on the
system by means of digital inputs and the analog target values.
Local operation = Command data set 0: In this case the command code of the terminal strip
P0700 Index 0 = 2 and the frequency target value is the analog target value P1000
Index 0 = 2.
Remote operation = Command data set 1: In this case the command code corresponds with
the control word (word 0) received from the PROFIBUS P0700 Index 1 = 6 and the
frequency target value corresponds with the control word 1 received from the PROFIBUS
P1000 Index 0 = 6.
