Bachmann LX800/DD512/CF512 – High-Performance Electronic HMI Display | MX-Series Platform
Engineering Background: The Bachmann MX-Series is a modular, real-time automation platform widely deployed in wind energy, power generation, marine propulsion, and industrial process control. The LX800/DD512/CF512 is the integrated electronic HMI (Human Machine Interface) assembly for this platform, combining a local display controller (LX800), a digital display driver board (DD512), and a compact flash storage module (CF512) into a unified operator interface solution.
Product Positioning: Designed for OEM machine builders and system integrators who require a ruggedized, deterministic HMI tightly coupled to Bachmann’s real-time control bus. This module eliminates the need for a separate panel PC, reducing cabinet footprint and improving system MTBF in harsh industrial environments.

Engineering Advantages
- Tight Platform Integration: Native MX-Bus coupling eliminates latency between controller and display — no OPC-UA or Modbus bridging required
- Modular Replacement: Each sub-module (LX800, DD512, CF512) can be replaced independently, minimizing downtime and spare parts cost
- Deterministic Real-Time Display: HMI refresh synchronized to MX controller scan cycle — critical for fast-process visualization
- Compact Footprint: Rack-integrated design eliminates external panel PC, reducing wiring complexity and cabinet space by up to 40%
- Long Product Lifecycle: Bachmann MX-Series components are supported with 10+ year availability commitments — essential for wind and power infrastructure
- IEC 61131-3 Native: HMI visualization programmed directly in SolutionCenter alongside PLC logic — single-tool engineering workflow
System Architecture & Signal Flow
The LX800 processor module mounts in the MX-Series rack and communicates with the master CPU via the high-speed MX-Bus backplane. The DD512 display driver conditions video signals for the connected operator panel, while the CF512 stores HMI application images, trend data logs, and alarm histories. Operator inputs (touchscreen or keypad) are processed by the LX800 and passed to the main controller via shared memory — achieving sub-millisecond HMI-to-controller response times.
Typical rack configuration: MX220/MX213 CPU → MX-Bus → LX800 (HMI CPU) → DD512 (Display Driver) → CF512 (Storage) → Operator Panel Display.

Technical FAQ
Q: Can the LX800/DD512/CF512 be used with older MX-Series racks (MX200 generation)?
A: Compatibility depends on backplane revision and firmware version. Please provide your rack serial number for confirmation before ordering.
Q: Is the CF512 storage pre-loaded with HMI application software?
A: Units are supplied as hardware only unless otherwise specified. Customer HMI application must be loaded via Bachmann SolutionCenter during commissioning.
Q: Can individual sub-modules (e.g., only DD512) be ordered separately?
A: Yes. Contact us with the specific part number required. We maintain stock of individual LX800, DD512, and CF512 modules.
Q: What is the typical failure mode for this assembly?
A: Most common failures are CF512 flash degradation (data corruption after 10+ years) and DD512 display driver capacitor aging. LX800 CPU failures are rare. Konmask recommends proactive CF512 replacement at 8-year intervals.
Q: Do you provide Bachmann SolutionCenter software or licenses?
A: We do not supply software licenses. Please contact Bachmann Electronic GmbH directly for SolutionCenter licensing. We can assist with hardware procurement only.
