CHAPTER 11
Data Logging
This chapter describes the CX-Supervisor data logging facilities including how to configure items to
be logged, the logging of data and the viewing and exporting of recorded data.
What is Data Logging
The concept of the Data Logger is the ability to define a number of points and expressions during
development which may be recorded while the CX-Supervisor project is being executed in runtime.
These events may be viewed at runtime and recorded for future evaluation. They may also be
exported to other programs such as Microsoft Excel.
The recorded events are stored in one or more Data Sets, which can then be viewed using the Data
Log Viewer. The events to be recorded are defined by the developer and any number of Data Sets
may be used to record specific areas or types of events either automatically at runtime or as specified
by the developer.
As an aid to viewing a number of particular events in isolation Data Sets can be subdivided into data
Groups. Specific areas of related data can then be stored in these groups which can then be viewed
either singly or with other groups within a Data Set.
The main elements of the CX-Supervisor Data Logger are:
♦ Data Logger Editor: used to configure items to be logged
♦ Data Logging at Runtime: the actual logging of the data
♦ Data Log Viewer: used to view the logged data
♦ Remote Data Viewer: enables viewing separately from the runtime system
♦ Data Log Export facility: enables export to other programs (e.g. MS Excel)
♦ Script Functions: gives full control over the logging process
Data Log Editor
Configuring Data Sets and Logging Settings
The Data Sets, data Groups and Items to log are configured from the Logging Tab on the
bottom of the Development Workspace editor. Items are edited using a right mouse-button
context sensitive menu. The option available from the menu are:
♦ Edit: enable the parameters of the selected Data Set, Group or Item to be edited.
♦ Cut, Copy, and Paste: enables the selected Item to be cut or copied and then pasted into a Data
Set or Group.
♦ Delete: will delete the selected entry.
