INVT INVT Workshop / AutoStudio for Bottle Filling

INVT Workshop and AutoStudio are the two programming tools for the IVC-series PLCs (IVC1, IVC2, IVC3) and the AX-series (AX70 etc.) respectively. The core IDE feel is FX-style — ladder, IL, and SFC editors with soft-element tables and offline simulator support — and the instruction set borrows from Mitsubishi FX conventions. INVT's heritage is in drives (variable-frequency and servo) rather than PLCs, and the engineering tools reflect that bias: drive-PLC integration is unusually clean, with a u...
