Schneider's automation software lives under the EcoStruxure umbrella — but it is two distinct engineering tools, one per controller line. Pick the wrong one and your controller won't even open. Here's how to keep them straight.
Both are EcoStruxure, both are IEC 61131-3 — but they target different hardware and feel different. Tap each to see what it's for.

🟢 Machine Expert — CODESYS-based engineering for the M221/M241/M251/M262 machine line; logic + motion for OEM machines.
🔵 Control Expert — the PAC engineering for M340/M580; tasks & sections, topological addressing, Hot Standby. (Tracks 01–08.)
🗣️ IEC 61131-3 — both speak the standard languages (LD, FBD, ST, IL, SFC), so the skills transfer even when the tool doesn't. (Track 03.)
🌐 One network story — Modbus & EtherNet/IP tie controllers, I/O and supervision together across both lines. (Track 06.)
You open a project for an M262 machine controller. Which Schneider tool do you reach for?
