Client Impact

Real Results for Industrial Operations That Cannot Afford Downtime


PartNexus™ helps industrial plants stabilise automation systems, reduce sourcing risk and restore predictable operation — even when OEM support has ended. Our impact is measured in reduced downtime, improved reliability and extended system life across legacy, obsolete and mixed‑generation environments.

Below are examples of how our engineering‑led approach delivers measurable operational improvement.

Person in suit giving a five-star customer satisfaction rating.

Stabilising Critical Production Lines

87% Reduction in Unplanned Downtime — Packaging Line

A packaging plant experienced recurring line stoppages caused by intermittent PLC and network instability.

PartNexus™:

  • Identified root‑cause failures in aging backplanes and connectors
  • Stabilised PLC communication and restored network integrity
  • Verified and supplied replacement modules for high‑risk components

Result: Production downtime reduced by 87% over the following quarter.

Restoring Legacy Control Systems

24‑Hour Recovery of a Failed Legacy PLC System

A plant running an obsolete PLC platform suffered a complete system failure. OEM support was unavailable.

PartNexus™:

  • Diagnosed the failure remotely within hours
  • Sourced verified legacy modules from traceable stock
  • Restored the system to full operation within 24 hours

Result: The plant avoided extended shutdown and resumed production the next day.

Eliminating Intermittent Faults in High‑Duty Environments

9‑Month Zero‑Fault Run After Stabilising a Critical Line

A high‑duty production line experienced intermittent drive trips and I/O instability.

PartNexus™:

  • Identified capacitor aging and vibration‑related I/O degradation
  • Stabilised drive performance and replaced high‑risk modules
  • Implemented a lifecycle extension plan

Result: The line achieved a continuous nine‑month run with zero automation‑related faults.

Reducing Sourcing Risk for Procurement Teams

Verified Replacement Strategy for End‑of‑Life Components

A procurement team faced repeated sourcing failures for discontinued PLC modules.

PartNexus™:

  • Verified component authenticity and traceability
  • Provided compatibility validation for replacement options
  • Built a risk‑based sourcing plan aligned with engineering requirements

Result: Procurement reduced sourcing risk and eliminated counterfeit‑related failures.

Improving Network Reliability Across Mixed‑Generation System

Restoring Visibility and Communication Stability

A plant with mixed‑generation PLCs and drives experienced intermittent network loss affecting production visibility.

PartNexus™:

  • Identified EMI‑related degradation and cable fatigue
  • Recovered network performance and stabilised communication paths
  • Implemented grounding and shielding improvements

Result: Network reliability improved significantly, restoring stable production visibility.

Extending the Life of Aging Automation Assets

Lifecycle Extension for Legacy Drives and HMIs

A facility operating aging drives and HMIs required a structured plan to avoid unexpected failures.

PartNexus™:

  • Assessed installed‑base condition
  • Identified high‑risk components
  • Developed a phased replacement and migration plan

Result: The plant extended the life of critical assets while preparing for controlled modernisation.

Why These Results Matter

Industrial operations choose PartNexus™ because our work delivers:

  • Predictable system behaviour
  • Reduced downtime and operational risk
  • Verified, traceable sourcing for critical components
  • Stability across legacy, obsolete and modern systems
  • Engineering‑aligned procurement decisions
  • Faster recovery from failures

Our impact is measured in operational continuity — not marketing metrics.
