Product Overview

The Siemens 6AV8100-0BB00-0AA1​ is a SIMATIC SCD 1297-ET – a 12.1-inch (30.8 cm) industrial TFT LCD monitor with integrated resistive touchscreen, engineered as a display peripheral for SIMATIC Industrial PCs (Box PC, Panel PC, Rack PC) and any PC-class controller carrying VGA and/or DVI video output. Within the SIMATIC 6AV8100 family, the SCD 1297 series occupies the 12-inch tier, offered in two mechanical formats: the -E/ET (flush-mount “Einbau” behind a cabinet door or front plate) and the -R/RT (19-inch rack-mount slide-drawer). The Siemens 6AV8100-0BB00-0AA1​ is the ET variant — “E” = flush-mount, “T” = mit Touch (with resistive touch); the non-touch flush-mount is 6AV8100-0BA00-0AA1 (SCD 1297-E). This distinction matters because many cabinet-door retrofits specify “SCD 1297” generically and then discover too late that the touch or rack variant was needed — the Siemens 6AV8100-0BB00-0AA1​ is the one with resistive touch for glove-operable interaction when paired with an IPC running WinCC Runtime, WinCC OA, or any HMI software stack hosted on the PC side.

Technically, the Siemens 6AV8100-0BB00-0AA1​ delivers an 800 × 600 SVGA TFT panel with 262,144 colours, 0.33 mm pixel pitch, 246 × 184.5 mm active area, and dual video input (15-pin HD VGA + 29-pin DVI-D) with an onboard scaling DSP that accepts non-native resolutions and maps them cleanly to the 800×600 raster — useful when the IPC’s output resolution drifts or when the monitor is reused across multiple IPC generations. The resistive touch layer routes back to the IPC via a dedicated touch interface (serial/USB class), turning the Siemens 6AV8100-0BB00-0AA1​ into a fully interactive terminal rather than a display-only device. Power is flexible: 12 V DC native (barrel input), 24 V DC via an optional DC/DC converter, or 100–240 V AC via an external AC/DC brick — but the -0AA1 is specified “W/O POWER SUPPLY”, meaning no AC/DC brick is included in the box; the buyer supplies 12 V or 24 V DC from the cabinet PSU or adds Siemens’ AC/DC accessory. Front protection is IP54 with UL1950 listing; the flush-mount bezel carries a continuous O-ring gasket that seats into a machined counterbore on the cabinet door or front plate.

Siemens has marked the Siemens 6AV8100-0BB00-0AA1​ as end-of-life / spare-part status, with a successor article 6AV8100-0BB00-1AA1 carrying the same SCD 1297-ET mechanical and electrical spec. Procurement today is therefore dominated by like-for-like swaps on lines where an SCD 1297-ET is already flush-mounted in a cabinet door, validated under GMP/FDA change-control, or where the 12″ 4:3 800×600 format is frozen because the HMI software (WinCC Runtime on the IPC side) was authored to that canvas and rescaling to 16:9 would trigger re-validation. We supply the Siemens 6AV8100-0BB00-0AA1​ as new-surplus, refurbished-tested or used-tested, with VGA/DVI signal loopback and touch-grid calibration verified on a SIMATIC IPC bench before dispatch.

Main Features and Advantages

Flush-mount industrial form factor with sealed front: The Siemens 6AV8100-0BB00-0AA1​ is delivered with a front plate and a continuous O-ring gasket that seats into a machined counterbore on the cabinet door or control-panel front plate. The “ET” suffix means the front plate integrates the resistive touch layer under the TFT, so the operator interacts directly on the glass through work gloves — a defining advantage over capctive panels that fail with gloved fingers. The IP54 front (UL1950 listed) resists dust and spray in stamping, packaging, food & beverage non-washdown zones, and water/wastewater kiosks. Because the rear of the Siemens 6AV8100-0BB00-0AA1​ sits behind the door (air circulation required, per the SCD manual), the cabinet interior must allow convection around the enclosure — the manual explicitly warns against blocking the rear.

Dual video input with scaling DSP: Many industrial monitors lock to a single VGA or DVI feed; the Siemens 6AV8100-0BB00-0AA1​ carries both a 15-pin HD VGA and a 29-pin DVI-D, selectable via OSD or auto-detect, with an onboard scaling DSP that accepts off-native resolutions (e.g., 640×480, 1024×768, 1280×1024 from an IPC’s BIOS/post screen) and maps them to the 800×600 panel without tearing or geometric distortion. This matters across the SIMATIC IPC family lifespan: an IPC347D might output 800×600 natively; a newer IPC477D or IPC627D defaulting to 1920×1080 can still drive the Siemens 6AV8100-0BB00-0AA1​ via DVI, with the DSP handling scale-down — letting plants keep the same 12″ door cut-out across a multi-generation IPC refresh without touching the cabinet.

Resistive touch as IPC peripheral: The Siemens 6AV8100-0BB00-0AA1​ does not run WinCC Flexible or TIA Portal on-board — it is a monitor, not an HMI panel. The resistive touch routes to the IPC via a dedicated touch interface (serial or USB class depending on cabling), where the IPC’s HMI runtime (WinCC Runtime Professional, WinCC OA, Zenon, Ignition, proprietary .NET HMI) picks up touch events. This architecture is the standard SIMATIC deployment model: IPC = compute + software, SCD monitor = display + touch. For plants that already run an S7-300/400/1500 + IPC + WinCC RT stack, the Siemens 6AV8100-0BB00-0AA1​ is the display half of that pair, and a failed unit swaps out in minutes: unbolt the front plate, disconnect VGA/DVI/touch/power, bolt the replacement, restore. No project recompile, no tag rediscovery — the IPC side is untouched.

Power flexibility without vendor lock: The Siemens 6AV8100-0BB00-0AA1​ accepts 12 V DC natively on a barrel connector (polarity-protected), 24 V DC via an optional DC/DC converter saddle, or 100–240 V AC through an external AC/DC brick (Siemens order-separately). The “-0AA1 = W/O POWER SUPPLY” means the AC brick is not in the box — most industrial cabinets already have 24 V DC rails (SITOP), so the panel taps the rail via the DC/DC saddle and the “no PSU included” is actually the cheaper/configurable SKU. For retrofits replacing an older SCD that came with the AC brick, the same brick often carries forward; for fresh installs, the buyer chooses 12 V / 24 V / AC based on cabinet topology.

CCFL backlight & lifecycle candour: The Siemens 6AV8100-0BB00-0AA1​ uses 2× CCFL backlight tubes, not LED. CCFL gives excellent colour evenness but has a shorter and less predictable half-life than modern LED panels, and Siemens’ discontinuation of the 6AV8100 SCD line is partly CCFL-component EOL. For 24/7 lines, budget backlight replacement or keep a spare Siemens 6AV8100-0BB00-0AA1​ on the shelf; for fresh-spec projects, the migration pointer is toward the newer SIMATIC Flat Panel monitors (6AV7880… series, LED backlight, wider format options) or the successor 6AV8100-0BB00-1AA1 if the 12″ 4:3 form factor must be preserved. We don’t pitch the Siemens 6AV8100-0BB00-0AA1​ as forward-spec — it’s a preservation/spare buy for existing SCD cut-outs — and we flag the LED-flat-panel migration at quotation.
