Error Information
If the set value is out of the range, a red error message Note: Please consider the setting ranges! appears
and the value changes back to the default setting.
If the set values do not follow the setting rules, a red error message Note: Consider setting rules: 'upper
threshold > lower threshold' and (upper threshold - lower threshold) > 2 * hysteresis appears and the
value changes back to the previous setting.
Value View of the Waveform Records
You cannot view the waveform records triggered by the other sources via the Web browser, but you can
download them. For more information, refer to chapter 7.3 File Download.
During the download progress, the selected files are stored by the browser. You can use the software SIGRA to
display the transmitted record data. For more information on SIGRA, contact the Siemens Hotline.
Clearing of Waveform Records
To clear waveform records, refer to chapter 7.2 Clearing of Data.
