7.2 Commissioning
The following objects are important for setting the time:
1. Local time of the controller
2. Local time of the operator panel (synchronization is only possible for real HMI)
3. Input fields for setting the CPU system time (please note the possible offset
between system and local time when entering; in the example project, project
system and local time are identical)
4. Button for accepting the set CPU system time
5. Ending runtime (for example, to make time zone settings in Windows CE)

Quick Start

The scale can be calibrated via the SIWATOOL configuration package
or via this screen.
You need a known weight which should be at least 5% of the rated load of the load
cell.
The SIWAREX WP231 weighing module is configured via the SIMATIC S7-1200 by
means of "write data record" as of firmware V1.1.
In order to configure the load cell and then to calibrate the scale, proceed as
follows:
Table 7-1
No.
1. Click the icon for the quick start menu in the
footer.
2. 1. By opening the quick start menu, the
weighing module is switched to service
mode.
2. Via the question mark you will receive
information about the quick start menu.
You have the option to continue the
configuration with the existing (3) or the factory
settings (4).
3. Click the button to continue with the
factory settings.
4. Enter the following parameters:
1. Weight unit: g (gram)
2. Maximum weighing range: 3000 g (rated
load E of the load cell = 3 kg)
max
3. Numerical increment d: 0.2 g (minimum
scale interval V
4. Calibration weight 1: minimum 5% of rated
load Emax
5. Save the values on the weighing module
6. Go to the next menu item.
The technical data of the load cell can be
found in the operating instruction for the
SIWAREX WL200 load cells (\4\).
