Logger Overview

The IDX Logger service operates as a regular IDX DM. It allows for relatively simple data logging/historian services.

Since the IDX logger is a DM it can be made to log any data passing through an IDX gateway to storage on the local platform. Logs are stored as Excel CSV-style text files which can be easily imported into data analysis tools such as Excel or the more powerful CSense, amongst others. The logger allows for tags to be logged according to a group membership which defines in which group file the data is stored. A tag index allows the data to be stored within the specified group file in any column position desired.

Tags can also be logged to a database in a datatable. The name of the datatable is defined in the set up of the groups. The datatable will be populated with columns Date,Tag1,Tag2 etc and everytime a line is logged to the csv file it will be logged to the database.

In addition, file sizes can be managed by controlling the number of days of logs that are retained before old data is overwritten. Further, logging speed has customisable millisecond resolution, meaning high-speed, high volume logging is possible. Finally, the logger permits customisation of log file structure, with new files being created every day, hour or 10 minute interval. This makes sorting through, finding and analysing specific data sets quicker and simpler.
