LED_O Industrial RGB Display
with Modbus TCP
Designed and built by Midlands Electronic Solutions in Stoke-on-Trent, UK, LED_O (also written LED-O) is a compact round RGB LED display and intelligent stack light for machine status, alarm indication, and industrial signage. Controlled by any PLC via Modbus TCP — or configured live from any browser via HTTPS.
Why LED_O?
Everything a PLC engineer or machine builder needs — out of the box, no middleware required.
Built-in HTTPS Web Interface
Commission and configure from any browser. Change display content, set alarm thresholds, and update network settings without touching the PLC program.
Alarm Display with Colour Change
Set high and low alarm thresholds. LED_O automatically switches colour when limits are breached — a direct replacement for traditional stack lights.
