Scale parameters and functions of the belt scale

8.1

Parameters and functions

The SIWAREX WP241 electronic weighing system can be used to design a belt scale in
accordance with OIML R50. Approval in accordance with MID will be available soon.
All parameters are set to default values in the factory. In the case of a previously used
electronic weighing system, you can restore the configuration to factory settings using the
"Load factory settings" command.
You can also create your own restore point. You can reload the saved configuration at a later
point in time with the "Load restore point" command.
The factory-set parameters are provided with typical values so that the scale can be
immediately calibrated following input of the rated data. The advantage of this solution is that
you can decide which typical values are to be retained and to what extent the response of
the scale has to be adapted.
All parameters are divided into data records (DR). The data records are organized in steps
(tasks) which constitute a functional unit during commissioning or during the process. Data
records can only be read or written as complete packages. Reading or writing of a single
parameter within a data record is therefore not possible. It is therefore recommendable to
proceed as follows before editing a parameter:
1. Read in the corresponding data record (to SIWATOOL or to the data block of the PLC)
2. Edit the desired parameter
3. Write the data record back into the weighing module
The scale functions influenced by the parameters are also described in the following
parameter description.
The parameters of a given data record are initially displayed in an overview table. A
description of their effect on the scale then follows.
When it receives new parameters, the SIWAREX module runs a validation check. In the
event of a parameter assignment error, the complete data record is not applied (not saved)
by the SIWAREX module and a data/operator error is reported.

DR 2 command code

DR 2 is a special data record only used to transfer commands to the SIWAREX module by
the SIWATOOL PC program.
