5.10.1 DR 15 - Tare Entry
DR 1
5 is used for external specification of the tare weight. Once specified with
DR 15, the tare value is not yet activated. The transfer to tare memory of the
SIWAREX FTC is then performed with instruction „Accept tare entry“
(see command code
24).
5.11 DR 16 Weight simulation entry
If the DR 16 was defined as the source for the weight simulation (see DR 7 Source
for the weight
simulation), defining a weight value through DR 16 will deactivate
the measurement input of the SIWAREX FTC and the defined value is "simulated"
as the weight value.
Procedures:
o Check in DR 7, whether DR 16 has been defined as the source for the weight
simulation
o Enter a value to be simulated
o Send the DR 16 to the scale

instead of the gross weight e.g. for test)

5.11.1 DR 16 - Weight Simulation Definition
If the DR 16 wa
s defined as the source for the weight simulation (see DR 7
Source
for the weight
simulation), defining a weight value through DR 16 will deactivate
the measurement input of the SIWAREX FTC and the defined value is "simulated"
as the weight value. This way, plant components (including filter settings) can be
tested even though the scale is not set up yet.
5.12 DR 17 Analog Output Control
If DR 17 has been defined as the source for the analogue output (see DR 7
Source for the analog output) then sending a weight value will output a
corresponding output stream on the analogue output.
Procedures:
o Check in DR 7, whether DR 17 was defined as the source for the analog output.
o Check the parameter definitions of the analog output (see DR 7
Weight for
zero point
and following parameters).
