sets

For many applications it is beneficial to have the possibility to change several
parameter settings simultaneous during operation or in the state ready to run with
an external signal. By indexing it is possible to set a parameter to several values
which can be activated by data set change-over. There are the following data sets:

Command data set (CDS)

P0810 =...

Command data set CDS bit 0 (local / remote)
Selects the command source in which bit 0 should be read-out to select a command data
set (CDS).

The currently active command data set (CDS) is displayed using parameter r0050.

P0811 =...

BI: CDS bit 1
Selects command source from which to read Bit 1 for selecting a command data set
(see P0810).

Example for CDS changeover:
CDS1: Command source via terminals and setpoint source via analog input (ADC)
CDS2: Command source via BOP and setpoint source via MOP
CDS changeover is realized using digital input 4 (DIN 4)

Steps:

1. Carry-out commissioning for CDS1 (P0700[0] = 2 and P1000[0] = 2)
2. Connect P0810 (P0811 if required) to the CDS changeover source

(P0704[0] = 99, P0810 = 722.3)

3. Copy from CDS1 to CDS2 (P0809[0] = 0, P0809[1] = 1, P0809[2] = 2)
4. Adapt CDS2 parameters (P0700[1] = 1 and P1000[1] = 1)
