The automation solution uses an S7-1200 controller and the SIWAREX MS
weighing module WP231 with a WL260 load cell. The weight value of the
packaged goods is recorded and compared with a reference value. After filling, it is
checked whether all components are complete. The packaged goods can be
clearly identified by a batch number.
The DataLog function of the S7-1200 controller makes it possible to log the
currently measured weight values with a time stamp in the flash memory of the
CPU.
You can download your data log files with the help of an internet browser (e.g. the
integrated Internet Explorer on the TP 700 Comfort TouchPanel) via the integrated
PLC web server of the S7-1200 controller.
Connecting the S7-1200 controller to a Windows PC enables automatic read out
the log data and the evaluation with common spreadsheet applications such as
Excel.
The individual stations of the filling process are monitored via screens that can be
switched to German or English using a TP 700 Comfort touch panel.
The recipes to manage the reference data of different production series are saved
in the load memory of the S7-1200 controller.
The configuration of the SIWAREX WP231 weighing module is performed via the
SIMATIC S7-1200 by means of "write data record" as of firmware V1.1.
