Scale parameters and functions
8.3 DR 3 Calibration parameters
SIWAREX WP251
Manual, 12/2015, A5E37203357A
75
The parameter defines the operating mode of the scale.
The following operating modes are available:
0: Non-automatic weighing instrument (NAWI) – Filling
1: Non-automatic weighing instrument (NAWI) – Removal
10: Automatic gravimetric instrument – Filling
20: Automatic catchweighing instrument - Filling
21: Automatic catchweighing instrument - Removal
SecureDisplay including weighing range data
In legal trade operation, the software version of the HMI device must be recorded so that it
can be checked by an official verification officer.
For applications requiring official calibration, the "SecureDisplay" software is used to display
the calibratable weight value. The parameter defines whether "SecureDisplay"
communicates directly via the Ethernet port of the WP251 or via the Ethernet port of the
SIMATIC S7-1200 CPU.
For applications requiring official calibration, the "SecureDisplay" software is used to display
the calibratable weight value. The parameter defines the version of the "SecureDisplay"
software that is running in the HMI device. If the version is not entered correctly, a weight
value will not be output in "SecureDisplay", and the display stays in the "Start Up" step.
Smallest zoom factor of SecureDisplay
The minimum display size defines the smallest zoom factor for the "SecureDisplay"
calibratable display. If the parameter does not match the smallest zoom factor in the .xml file
in the HMI device, "SecureDisplay" remains in the "StartUp "step and no weight value is
output.
The parameter defines the line frequency of the power supply grid. A selection between 50
Hz and 60 Hz can be made. By making the correct setting, interferences caused by the
power supply grid can be better suppressed.
