Industrial PLC Programming: Specialized Engineers Available per Project — No Overhead

Finding a qualified PLC engineer who’s available when you need them — without the commitment of a permanent hire — is harder than it sounds. At HAAC Technologies we solve that with a straightforward model: specialized PLC programming engineers, available by the hour, by project, or on a support contract — no fixed costs, no idle time, no learning curve.

We work with the three dominant platforms in the industry: Siemens, Schneider Electric, and Rockwell Automation (Allen-Bradley), allowing us to integrate into virtually any plant regardless of equipment brand.

The Problem We Solve

Many plants face the same dilemma: they need PLC expertise but not on a permanent basis. Hiring a staff engineer means salary, benefits, and recruitment time. Calling the original equipment vendor means slow response times and high costs. Improvising with available staff means risks no production manager wants to take.

Scenarios where our model makes immediate sense:

  • You have a new automation project and need specialized programming without hiring
  • Equipment failed and your internal team doesn't master that PLC platform
  • You want to optimize the control logic of an existing machine to improve performance
  • You're expanding the plant and need additional engineering capacity for a defined period
  • You need to document and standardize the programming of your current equipment

What Our Engineers Do for Your Operation

Real experience in PLCs, SCADA, and control systems

We don't send technicians who know the manual — we send engineers with hands-on experience in real industrial automation projects. Each one masters at least one primary platform and follows programming standards that guarantee clean, documented code that any technician can maintain afterward.

They integrate into your team without friction

Our engineers arrive ready to work: they understand the industrial context, respect plant safety protocols, and adapt to your operation's timelines and priorities. You don't need to explain how a plant works — they already know.

You pay only for what you need

No permanent hiring, no benefits, no unproductive time. The hourly or project-based model gives you access to senior expertise with total budget flexibility. Scale up when the project demands it, scale down when it ends.

Code that meets standards, not just "works"

We apply efficient, documented programming standards: consistent naming, reusable blocks, clear comments, and a structure that makes future maintenance straightforward. The result is a program any engineer can understand and modify — not just the one who wrote it.

Siemens

TIA Portal / S7

The most widely used platform in global manufacturing. We master TIA Portal for S7-1200, S7-1500, and legacy series, with experience in PROFINET communication, WinCC integration, and migration projects from older platforms.

Schneider Electric

EcoStruxure / Modicon

Specialists in the EcoStruxure suite and the Modicon M340, M580, and Quantum families. Ideal for plants with Schneider infrastructure that need optimization, expansion, or specialized technical support.

Rockwell Automation

Allen-Bradley / Studio 5000

One of the most prevalent brands in Mexican plants with North American influence. We work with the full ControlLogix, CompactLogix, and MicroLogix families, with experience in FactoryTalk integration and EtherNet/IP networks.
