Commissioning
7.3 Automatic quick calibration with SIWATOOL
7.3.4
Input of required parameters
For commissioning, you must enter the following parameters in data record DR 3 and send
these to the module:
● Unit of weight
● Required maximum weighing range of the scale
● Scale interval
The description of the parameters can be obtained from the description of data record DR 3.
Sending/receiving a data record is always carried out by right-clicking on the data record
name in the "Value" column in the tree structure.
For example, if data record 3 is to be sent, right-click on "Calibration parameter (DR3)". A
submenu is then opened with the option for sending the respective data record to the
weighing module or for reading it from the module. All data records can only be sent as
complete packets to the SIWAREX or read from it. It is not possible to read or write individual
parameters within a data record. Therefore the complete data record must initially be
received for every change to parameters within it. The desired parameter can then be edited,
and the data record returned. If the data record is not received, the danger exists that
different offline parameters will be sent to the scale and overwrite previously active and
intentionally defined parameters.
You must subsequently enter the required parameters in data record DR 10 and send these
to the module.
