Landing page captured for the 2026-09-28 issue.

For: Teachers and students in industrial-automation classrooms
Worth noticing: The page says classes can save 99 programs, while a teacher PIN controls uploads to the connected board.

Field notes

The page lays out a classroom workflow: students can test with on-screen switches, sliders, and indicators before wiring hardware, while the teacher retains control over loading programs. Its examples include a thermostat and a parts counter, and the listed hardware options are an UNO R4 WiFi or a Mega 2560 with an Ethernet shield. A dated version note describes Wi-Fi changes and LADDER display refinements.
