Phil Turmel, from Automation Prefessionals, has been working on some interesting new Ignition modules.
The Time Series Database Cache module was recently released on Module Marketplace.
The Time Series Database Cache module supplies dataset manipulation and database query functions that are optimized for use with large and/or high-resolution database tables containing timestamped data.
Check out the documentation for more details.
Simulation Aids Module
Phil recently released a public beta of a new Ignition module called the Simulation Aids Module. This module helped Phil test projects in-house when physical components were off-limits or didn't exist yet. See Phil's post on the forum about it.
