This document can also be applied when using a SIWAREX WP241 since the identification 
mechanisms are identical. 
 
11.2  Parameters and functions 
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.
