Application Scenarios
In a cement plant central control room in Southeast Asia, the DCS operator previously juggled three stacked 12-inch HMIs to watch kiln inlet/outlet temperatures, cooler grate speed, and raw-mill vibration on separate screens—context-switching that cost 10–15 seconds every alarm. Retrofitting two 6AV2124-0UC02-0AX0 panels let the engineering team tile four live trend windows, an alarm banner, and a motor-status mosaic on one 1366 × 768 page. The 18.5-inch real estate meant the kiln Foreman could stand two meters back and still read thermocouple deviations—something the old 12-inch units never allowed. When one panel needed a same-day swap during a scheduled kiln stop, the maintenance crew cloned the WinCC project to SD, popped the new 6AV2124-0UC02-0AX0 in, and rebooted—no laptop on the control-room floor, total downtime under 18 minutes.

Technical Principles and Innovative Values
- Innovation Point 1 – “God’s-eye” multi-window tiling on the shop floor. The 6AV2124-0UC02-0AX0 is one of the few HMIs in the Comfort class where a single screen can host four simultaneous trend objects, a 6000-alarm buffer, and a faceplate mosaic without scrolling—cutting operator context-switching on large lines (automotive body shop, cement kiln, steel rolling) by a measurable margin.
- Innovation Point 2 – Integrated 2-port PROFINET switch, again. Like its siblings, the 6AV2124-0UC02-0AX0 bakes the Ethernet switch into the RJ45 pair, so you can daisy-chain S7-1500 racks or distributed I/O through the HMI instead of buying a DIN-rail switch per panel row.
- Innovation Point 3 – X86 horsepower for scripting & media. The X86 core (not ARM as on Basic panels) lets the 6AV2124-0UC02-0AX0 run up to 200 VBScript/C-Script instances, host embedded IE viewer, PDF/Excel viewers, and Sm@rtServer VNC—all relevant when the panel doubles as a line-side terminal for maintenance docs.
- Innovation Point 4 – Portrait or landscape mounting. Unlike many 19-inch peers that lock to landscape, the 6AV2124-0UC02-0AX0 supports both orientations—useful on narrow electrical-house walls or vertical Andon totems where width is constrained.
- Innovation Point 5 – SD-card “no-PC” swap. Two SD slots let you carry a golden-image card for the 6AV2124-0UC02-0AX0—panel replacement on a weekend shift doesn’t need a PG laptop on-site.
