7.5.2
Offline parameter assignment
All scale parameters can be edited and saved without an electronic weighing system.
This reduces the setup time. You can thus prepare the parameters for several scales in your
office, and subsequently transfer them to the electronic weighing system during setup.
Data from one scale currently in operation can be exported and used to set up another scale.
7.5.3
Online parameter assignment
To switch to online mode, connect the PC to the SIWAREX module via an RS485/USB
converter. Set the appropriate interface in the communication menu.
You can change all parameters in the SIWAREX module in online mode. The message
window shows the current contents of the message buffer of the SIWAREX module. The
current process values are displayed in the "Online" column.
For test purposes, you can send various commands to the SIWAREX module. Differences
between the online/offline data are marked in red by SIWATOOL. This affects both the
associated data record and the individual parameter.
In order to archive data, all data can be exported from the SIWAREX module and saved as a
file or printed.
Note
You can edit all data in the SIWAREX module in online mode. The changes are not
automatically imported to the corresponding scale data block in the SIMATIC CPU.
To download the data to the SIWAREX module, select the data record with a right mouse
click and send it explicitly to the SIWAREX module.
Online parameter trends can be recorded and played back using the recorder function
located at the top right-hand edge of SIWATOOL. You can use the "Configure recorder"
button to select the data records to be recorded and to set the save parameters. The
playback speed can be set using a slider.
