How VEM handles Schneider

VEM connects to Schneider controllers through EcoStruxure Control Expert (formerly Unity Pro) and Modbus/TCP, capturing the full project — sections, DDT definitions, IO configuration and hot-standby settings — on every backup. Modicon M340, M580 and Quantum are all supported. See the broader VEM platform for how this fits alongside testing, validation and audit.

/ Typical application

Configuration management across distributed Modicon assets — unauthorised or unintentional changes surfaced the same shift they happen, not at the next audit.

/ 02 — Coverage

What gets captured

/ Captured

PLC code

Full Schneider project — routines, function blocks, ladder, ST.

/ Captured

HMI tags & screens

Tag databases, screen definitions, alarms, recipes, permissions.

/ Captured

Recipe data

Production recipes, setpoints, batch parameters — versioned alongside code.

/ Captured

Machine parameters

Drive parameters, IO config, network topology, safety, firmware fingerprints.
