PLC Programming

Scope of Work

Full-service PLC programming from concept through commissioning. We're not just coders - we understand the process, the equipment, and the production goals.

• New system design and programming
• Legacy system migrations
• Modifications and enhancements
• Troubleshooting and optimization

Deliverables

• Fully tested and commissioned programs
• HMI/operator interface development
• I/O configuration and checkout
• Complete documentation package
• Operator and maintenance training

Project Scale

Single-machine controls up through multi-line system integration. Typical projects range from $15K modifications to $300K+ new system builds. We've programmed standalone packaging equipment and coordinated controls across full production floors.

Response Time

For existing customers with support agreements, same-day remote access. On-site within 24-48 hours for urgent needs. For planned projects, we typically begin work within 2-4 weeks of signed PO depending on scope.

Team Depth

We're not a body shop. Our senior engineers handle projects directly - you're not getting a junior learning on your dime. For larger projects, we scale with trusted partners we've worked with for years.

Coverage Area

Based in Nashville. Primary coverage across Tennessee, Georgia, Alabama, Kentucky, the Carolinas, expanding into Arkansas and Missouri. We travel nationwide for the right projects.

Built for Your Team

We build for the maintainer, not for job security. Clean code with meaningful tag names (not "Tag001"). Structured programs with clear fault handling. Documentation that actually matches what's installed.

What "Documentation" Actually Means

• Commented code explaining the WHY, not just the WHAT
• I/O lists with terminal numbers, wire colors, device descriptions
• Network architecture diagrams
• Backup files in organized folders
• HMI navigation guides for operators

After Commissioning

We don't disappear. Standard support window for punch-list items. Phone and remote support for questions. Optional support agreements for ongoing access. When your team calls with a question, someone who actually worked on the system picks up.

Training

We'll walk your technicians through the program logic, fault recovery procedures, and common troubleshooting scenarios. Not checkbox training - actual knowledge transfer so they can own it.

Code Standards

We follow ISA-88/95 concepts where applicable. Structured text for complex logic, ladder for I/O and intuitive troubleshooting. Add-On Instructions (AOIs) for reusable logic blocks. UDTs for consistent data structures. Version-controlled program archives.

Approach to Existing Systems

Full backup before we touch anything. Compare documentation to actual configuration - they're rarely the same. Understand the process before changing the code. Test changes offline when possible, controlled cutover when not.

The Stuff That Matters

We actually understand scan time implications. We know why your AOI shouldn't be calling another AOI in a loop. We've dealt with Logix5000 memory fragmentation issues. We've migrated PLC-5 systems with indirect addressing nightmares. We've debugged ControlNet networks that were working "fine" until they weren't.
