LAUER 920 Series Technical Notes

The Evolution of 920 Series Architecture

The LAUER 920 Series was introduced as a successor to earlier LAUER PCS (Process Control System) terminals, transitioning from purely membrane-keypad interfaces to hybrid touch/keypad designs. Early variants in the 920 range used monochrome STN LCD displays with character-based rendering, communicating via RS-232 at baud rates up to 19,200 bps. Mid-generation units introduced graphical display capability with pixel-addressable screens and expanded protocol libraries. The 920.100.x sub-series, to which the 920.100.2 belongs, represents the resistive touch screen branch of the family, integrating a touch overlay onto the base LCD panel for direct on-screen input without dedicated function keys.

Compatibility across the 920 Series is governed by the LAUER PCS protocol stack and the proprietary LCA (LAUER Communication Adapter) interface. Panels within the same sub-series share backplane pinouts and power supply requirements (typically 24V DC), but firmware versions are not universally interchangeable across sub-series boundaries. Engineers replacing a 920-series unit must verify the exact sub-series designation, firmware revision, and communication protocol configuration before substitution. As the 920 Series has entered end-of-life status with LAUER (now operating under the Pilz group umbrella for certain product lines), cross-referencing to modern equivalents requires careful functional mapping.
