How VEM handles Beckhoff

VEM connects to Beckhoff controllers via ADS, capturing TwinCAT 2 and TwinCAT 3 projects in full — PLC code, EtherCAT topology, NC axis configuration, safety projects and TwinSAFE parameters — with the same scheduled and event-driven backup model used for every other vendor. See the broader VEM platform for how this fits alongside testing, validation and audit.

/ Typical application

Baseline comparison across TwinCAT projects: every recipe and parameter change captured, diffed and reviewable against the last known-good version.

/ 02 — Coverage

What gets captured

/ Captured

PLC code

Full Beckhoff 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.
