5.10.1 DR 16 - Weight simulation entry
If the DR 16 has been defined as the source for the weight simulation (see
Source for the weight simulation
) then the measurement input of the
SIWAREX FTA is deactivated by defining a weight value with the DR 16 and the
defined value is “simulated” as a weight value. This way, system components can
be tested although the scale is not yet completely constructed.
5.11 DR 17 Analog Output Control (NAWI, AWI)
If DR17 has been defined as the source for the analog output (see DR 7
) then sending a weight value will output a corresponding output
stream on the analog output.
Procedure:
o
Check for whether DR 17 has been defined as the source for the analog output
in DR 7
o
Check the parameter definition of the analog output (see DR 7
).
o
Enter value in DR 17
o
Send DR 17 to the scale

5.11.1 DR 17 - Ext. Definition for Analog Output
If the DR 17 has been defined as the source for controlling the analog output (see
DR 7 - Source for the Analog Output
) then the analog output is controlled with the
defined value with a definition of a weight value on DR 17. This way, the analog
output can be set via SIWATOOL.
5.12 DR 18 Control Display (NAWI, AWI)
A value can be defined through DR18 which is to be shown on the remote display.
This way, the SIEBERT remote display can be used for displaying values that are
calculated in the SIMATIC.
Procedure:
o
Enter value in DR 18
o
Send DR 18 to the scale
