Preset tare weight 1
Up to three tare weights can be entered. If a tare weight is to be applied, it must be enabled
with the corresponding command. The tare weights may not exceed the maximum values
specified in data record DR 3.

DR 16 Weight simulation
8.16.1
Overview
Specifying a weight value using data record DR 16 disables the measuring input of the
SIWAREX module and "simulates" a weight with the specified value. The SIWAREX module
must first be enabled for simulation mode in DR 3 and then switched to simulation mode with
command 3 ("Weight Simulation on"). Command 4 ("Weight Simulation off") switches the
module back to normal mode. In DR 30 Process State, a "Simulation mode" bit is available
that indicates whether or not the module is currently in simulation mode.
Procedure
● Enable simulation mode in DR 3
● Enter a weight value to be simulated in DR 16.
● Transfer DR 16 to the SIWAREX module
● Start the simulation using command "Weight simulation on (3)"
● Stop the simulation using command "Weight simulation off (4)"
