Scale parameters and functions
8
8.1 Parameters and functions
All parameters are set to default values in the factory. You can restore the configuration to
factory settings using the "Load factory settings" command.
The scales are ready for operation with the default parameter settings. You do not need to re-
enter all parameters. The advantage of this solution is that you can decide the default values
to be retain and the parameters that need to be adapted for your application.
All parameters are divided into data records (DR). The data records are organized in steps
(tasks) to be implemented during commissioning or during the process.
The scale functions governed by the parameters are also described in the parameter
description below.
First, the parameters of a given data record are displayed in a table. The detailed parameter
description for the parameters of this data record then follows.
When it receives new parameters, the SIWAREX module runs a validation check. In the event
of a parameter assignment error, the data record is not applied (not saved) by the SIWAREX
module and a data/operator error is reported.
8.2 Assigning parameters to the electronic weighing system with
SIWAREX DB
Introduction
You can assign parameters to the SIWAREX WP electronic weighing systems using the
SIMATIC HMI, the SIWATOOL or the SIMATIC S7 control system. The procedure described for
you is oriented to the data records (DS) from SIWATOOL and the SIMATIC S7 control system.
Procedure
1. Set the Load cell type parameter to SIWAREX DB in data record DR03. (Not relevant for
SIWAREX WP321)
2. Set the RS 485 protocol parameter to SIWAREX DB and the RS 485 baud rate to 115 200
bits/s in data record DR13.
3. Activate the load cell input for every connected load cell in the data record DR70.
4. Specify whether 4- or 6-wire load cells are connected for the Sensor type parameter in data
record DR70.
