A data or command error is signaled if a command cannot be executed or if the sent data
record is rejected.

Description
Turn on service mode
Turn off service mode
Turn on test mode. The simulation value from data record 16 is used in-
stead of the measured value for calculation of the process values. Simula-
tion mode must be enabled generally in DR 3 beforehand.
Switch off test mode.
The command resets the SIWAREX to the "ex works" status. During this
process:
All parameters and saved data (including log memory, logbook, IP
•
addresses and Modbus addresses)
All message buffers (diagnostic buffer, trace memory, etc.) are reset
•
A configured recovery point, if any, is overwritten with default settings.
•
Like "Load factory settings" (command code 11), but interface settings for
Ethernet and Modbus RTU are not reset to the factory setting.
Backs up all scale parameters as a recovery point that can then be loaded
when needed using command 31.
Calibration point 0 valid / save values for calibration point 0. The current
load cell signal or the currently measured digits are assigned to calibration
weight 0 from DR 3 and entered as "Calibration digit 0" in DR 3.
Calibration point 1 valid / save values for calibration point 1. The current
load cell signal or the currently measured digits are assigned to calibration
weight 1 from DR 3 and entered as "Calibration digit 1" in DR 3.
Calibration point 2 valid / save values for calibration point 2. The current
load cell signal or the currently measured digits are assigned to calibration
weight 2 from DR 3 and entered as "Calibration digit 2" in DR 3.
Move calibration characteristic. The command defines the current weight
of the scale as the new zero point (0 kg) and shifts the entire characteristic
curve without changing the slope. The command can be used, for exam-
ple, in order to compensate parts used for mounting calibration weights on
the scale at the end of the calibration.
Calculation of scale characteristic using the load cell parameters from data
record 10. The calculated characteristic is entered directly in data records
3 and 4 and is thus immediately active following execution of the com-
mand. The scale must be empty when the command is executed. The
accuracy of a scale that is automatically calibrated depends heavily on the
mechanical setup!
