Historical Data Display
In actual use, data generated from PLC or other connected equipment can update at any time, such as alarm. When it comes to historical data, we can use the historical data collector in SKTOOL to observe the historical data.
SKTOOL provides the function of historical data collector. Enter the Historical data collector dialog box in the project manager. If it is a new project, right-click the "Historical data collector" to add one; then double-click "Historical Data Collector 0" to enter the setting dialog box. For details, refer to properties of "History Data Collector" in Chapter 6.
