PLC & HMI Programming Services

Where Engineering Precision Meets Operational Intelligence

At Liberty Automation, we believe powerful automation doesn’t need to be complicated.
Our PLC and HMI programming delivers high functionality through clean, transparent design, giving manufacturers reliable performance and complete system ownership.

While others build proprietary code that locks clients into dependency, Liberty engineers create intuitive, open-architecture software that your maintenance team can understand, modify, and maintain with confidence.

Robust Performance Architecture: Functionality Without Complexity

Liberty Automation systems are built for industrial reliability and predictable performance under demanding conditions.

Each program incorporates:

Multi-layered error handling that identifies issues before they impact production.
Real-time process optimization through advanced PID loops and adaptive control logic.
Integrated safety systems designed to meet SIL and functional safety standards.

The result: control systems that run smarter, recover faster, and maintain consistent performance across your operation.

Complete Transparency: Your System, Your Control

Liberty Automation software is never locked or password-protected unless you specifically request it. You always receive full editable source code, comprehensive documentation, and complete system visibility.

That’s not a small detail, it’s our philosophy. We believe manufacturers should own their automation, not rent it.

With every project, you receive, all source code with full editing rights and no licensing restrictions as well as complete documentation, including functional specifications, I/O lists, and commissioning reports.

This transparency empowers your team to maintain, improve, and scale your system independently, without hidden costs or barriers.

Legacy System Mastery: Preserving Your Investment

Many manufacturing facilities rely on older control systems that still work, but need updates, optimization, or integration with newer technology.

Liberty Automation specializes in legacy system modernization, adapting original programming styles and logic structures to maintain operational familiarity while improving performance and reliability.

Our engineers combine reverse-engineering expertise with modern best practices to extend system life without disrupting proven workflows.

Our Legacy Modernization Approach

Code archaeology:

Documenting and mapping existing logic even when original references are incomplete.

Style pattern recognition:

Preserving the look and logic of your existing system while upgrading functionality.

Incremental modernization:

Phased updates that minimize downtime and maintain production continuity.

Knowledge transfer:

Ensuring your team understands both the legacy logic and the new functionality.

The Liberty Automation Competitive Advantage

Liberty doesn’t build dependency, we build capability. Our programming philosophy ensures you own your systems, understand your software, and can maintain them confidently for years to come.

What Sets Liberty Apart

Reduced Total Cost of Ownership: No proprietary software or forced upgrades.
Enhanced System Reliability: Clean, modular architecture simplifies troubleshooting.
Future-Proof Scalability: Designed for easy expansion as operations evolve.
Operational Independence: Empowering your team with the knowledge and tools to sustain performance.

Engineering Excellence Backed by Industry Standards

Liberty Automation’s programming practices adhere to recognized global standards that ensure quality, maintainability, and safety:

ANSI/ISA-101.01-2015 — HMI design principles.
ISA-18.2-2016 — Alarm management best practices.
IEC 61131-3 — International PLC programming standards.

Compliance with these frameworks guarantees our code is consistent, well-documented, and compatible across platforms, ensuring long-term support and performance.
