Technical Specifications

Solving the Discontinued Hardware Crisis

The LAUER PCS 695 was deployed extensively in manufacturing environments running legacy PLC architectures — particularly in machinery integrated with Siemens S5 controllers and equivalent serial-bus systems common in European industrial installations from the 1990s through the early 2000s. In these environments, the operator panel is not a peripheral — it is the primary human interface for process control, alarm acknowledgment, and parameter adjustment.

LAUER ceased production of the PCS series, and the PCS 695 is no longer manufactured or supported by the OEM. This creates a structural vulnerability for any facility still operating equipment dependent on this panel. There is no software-only workaround. A failed PCS 695 cannot be substituted with a modern touchscreen HMI without significant engineering effort: the communication protocol must be reverse-engineered or adapted, the PLC program may require modification, and the physical mounting and wiring must be reworked. In a facility running three shifts, this engineering process alone can consume weeks.

Condition & Reliability Assurance

All LAUER PCS 695 units supplied by DriveKNMS pass a structured 5-step quality process before dispatch:

1. Visual and mechanical inspection: Housing integrity, connector condition, and keypad or display surface are examined for damage, corrosion, or contamination.
2. Electrolytic capacitor assessment: Aging electrolytic capacitors are a primary failure mode in panels of this era. Units are inspected for capacitor bulging, leakage, or ESR deviation. Where warranted, capacitors are replaced with specification-matched components.
3. Pin and connector corrosion check: All interface connectors are inspected under magnification. Oxidized contacts are treated or the connector assembly is replaced to ensure reliable signal integrity.
4. Firmware version verification: The firmware version present on the unit is identified and documented. This information is provided to the customer to confirm compatibility with their installed PLC before dispatch review.
5. Functional power-on test: Where test fixtures permit, units are powered and basic display and communication functions are verified prior to packaging.

Key Features for System Maintenance

How do I confirm the unit is new or professionally refurbished — not a field-pulled scrap unit?
Each unit is accompanied by a condition report stating its classification (NOS, Tested Surplus, or Refurbished), the results of the 5-step QA process, and the firmware version. This documentation is provided before payment is required.
