PLC Programming Services
PLC Programming Services for Complex, Custom Systems
At Hallfield Controls, we provide PLC programming services for customers who need more than basic code development. Whether you need help on a new project, support for an older control system, or specialized expertise your internal team does not have in-house, we provide the technical depth needed to move the project forward with less risk. We support electrical engineers and industrial engineers on custom systems where programming must work reliably with the physical equipment, electrical design, and commissioning process.
PLC and HMI Programming Across Major Platforms
Programming has become one of Hallfield Controls’ core competencies because nearly every controls application depends on reliable logic, clear interfaces, and practical startup support. We routinely develop PLC and HMI programs from the ground up, modify existing applications, recover programs from failing hardware, and convert code from one platform to another when project requirements demand it.
Our programming experience includes major platforms such as:
- Allen-Bradley
- GE
- Siemens
- Horner
- AutomationDirect
- Phoenix Contact (including Linux-based PLCnext)
We also support projects involving motion control, distributed networks, and machine safety hardware where the programming must align with broader system requirements. That makes Hallfield Controls especially valuable on custom applications where the code cannot be treated as a standalone task.
- Machine Breakdown and Troubleshooting: We offer expert-level resolution for failed automation components.
- Automation Upgrades and Modernization: We help you redesign or upgrade outdated control systems to improve equipment longevity and overall system efficiency.
- Machine Safety Upgrades: Our team implements controls-related safety improvements and interface updates to support safer, more reliable equipment operation.
- Capacity Augmentation: We act as an outsourced electrical engineering department when your internal team is at maximum capacity or lacks specific controls expertise.
PC-Based and Embedded Programming for Specialized Applications
When a project demands more flexibility, faster data acquisition, or heavier data handling than a standard PLC platform can deliver, Hallfield Controls provides advanced, non-standard software architectures.
This approach is ideal for test, measurement, and validation-heavy environments where process control and data architecture must work seamlessly together. We support advanced data collection, reporting, SQL integration, web services, and high-speed acquisition using Visual Studio (C# and Visual Basic .NET) and National Instruments LabVIEW.
Offered on a case-by-case basis, we provide specialized development for applications falling outside standard PLC or PC environments, as well as hybrid Linux-based PLC environments. Our capabilities include:
- Windows Embedded and Windows CE
- STW Technic and Rabbit Semiconductor
- Custom C-language development and libraries to extend the functionality of next-generation, Linux-based PLCs (such as Phoenix Contact PLCnext)
Programming Support for Upgrades, Troubleshooting, and Commissioning
Hallfield Controls helps customers with more than greenfield programming work. We support upgrades to older PLC models, adjustments to existing programs, and troubleshooting for systems where internal teams have run out of ideas and need deeper controls expertise. We also support programming through test and debug, so the code is better aligned with actual machine function before final commissioning begins.
Why Choose Hallfield Controls?
Engineering-First Approach
