The latest ToolKit 7 comes with many great new features, which are documented here:

Additionally was a Software licensing model introduced, which impacts the Power Generation products in the following way:

Basic license is included free of charge in the ToolKit download. This basic software license enables users to configure, monitor, and troubleshoot on easYgen, LS-5, LS-6, MFR-300 and similar controllers.

Advanced license (part number 8447-5002) includes the following:

• All the features of the Basic license
• Unlimited plots per trend chart and trend on the fly windows (3 plots are included in the basic license)
• Allows to open plots as well
• Unlimited data log view plots
• Unlimited calculated plots
• Export all data logged parameters to a test file even if not charted

Toolkit 6 will remain available for those who prefer to work with the older version (it will only work on the older .wtools)
