Modernization Goes Beyond PLC-5 & SLC Migration

While PLC-5 and SLC migrations are common modernization drivers, many facilities are also facing broader challenges across their automation environment. Aging systems can increase operational risk, limit visibility, raise maintenance costs, and create cybersecurity concerns.

Common modernization priorities include:

  • Obsolete HMI and SCADA platforms
  • Unsupported hardware and software
  • Industrial network limitations
  • Cybersecurity vulnerabilities
  • Limited production visibility
  • Increasing maintenance costs

Our assessment helps identify risks, prioritize upgrades, and create a practical roadmap for improving reliability, performance, and long-term supportability.


Trusted by the World’s Leading Manufacturers

We partner with global leaders across food & beverage, life sciences, consumer products, and industrial manufacturing to plan and execute complex automation modernization projects with minimal disruption to operations.

Our CSIA Enterprise Certification, achieved across every E Tech Group location, means your modernization initiative is guided by proven, standardized processes. The result: lower risk, better visibility, and consistent execution from initial assessment through project delivery.

Our team will evaluate your existing automation environment and identify:

  • Obsolete hardware risks
  • Downtime vulnerabilities
  • Upgrade and migration opportunities, including PLC upgrade services
  • Quick wins to improve performance across your process automation solutions

The Risk of Legacy Automation Systems

Legacy systems create growing operational risk:

  • Increasing unplanned downtime
  • Unsupported or obsolete hardware
  • Limited visibility into production data
  • Cybersecurity vulnerabilities
  • Rising maintenance costs

What worked five years ago may now be your biggest operational risk, making it harder to drive modernization across your facility.

FAQ

PLC modernization is the process of upgrading obsolete automation hardware and software to improve reliability, cybersecurity, maintainability, and operational performance. Many manufacturers begin with a legacy PLC replacement strategy for unsupported PLC-5 and SLC systems.

PLC upgrade services include hardware replacement, migration planning, program conversion, testing, commissioning, documentation, and lifecycle support. E Tech Group helps manufacturers execute upgrades while minimizing downtime and production risk.

An SLC conversion is the migration of legacy Allen-Bradley SLC 500 systems to modern control platforms such as ControlLogix or CompactLogix. These projects help manufacturers reduce risk associated with unsupported hardware and improve long-term reliability.

Process automation solutions help manufacturers standardize operations, increase visibility, improve quality, reduce downtime, and support data-driven decision-making. Modern automation platforms provide a scalable foundation for continuous improvement initiatives.

Yes. E Tech Group helps manufacturers connect operational technologies with business systems to improve reporting, analytics, and decision-making through integrated business process automation solutions.

Yes. Our engineers help manufacturers integrate plant-floor systems with enterprise technologies to support IT process automation, IT operations automation, and broader operations automation strategies that improve efficiency and visibility across the organization.
