PLC Programming & Controls Engineering
Control logic you can read, maintain, and extend. We write new machine programs, retrofit aging systems, and bring structure to code that has grown wild over twenty years of patches.
Platforms we work on
- Rockwell / Allen-Bradley: deep expertise in Studio 5000, ControlLogix, and CompactLogix, including Add-On Instructions, structured modular code, and FactoryTalk View HMI integration.
- Beckhoff TwinCAT: PC-based control and EtherCAT systems.
- Industrial networks: EtherNet/IP, Modbus TCP, OPC UA, and MQTT Sparkplug B, so your controllers talk to everything else in the plant.
What our PLC work covers
- New machine programs: complete control logic for OEM machine builders and in-plant projects, from I/O design through commissioning.
- Retrofits and migrations: replacing obsolete controllers and drives while production keeps running, with tested cutover plans.
- Modular code standards: ISA-88 aligned structure, Add-On Instructions, and equipment modules, so every machine in your plant reads the same way and new engineers ramp up fast.
- Troubleshooting and rescue: intermittent faults, undocumented logic, and machines nobody dares touch. We find root cause and document it.
- Panel design: electrical design and control panels engineered alongside the code, not thrown over the wall.
Code your team can own
Every program ships with documentation: commented logic, tag standards, network drawings, and parameter records. Our goal is that your maintenance team can troubleshoot at 2 AM without calling us, and that when you do call, we already know the system.
Who we work with
Plantwide Integration is an independent systems integrator based in Big Lake, Minnesota, serving manufacturers and OEM machine builders across the Twin Cities, St. Cloud, Central Minnesota, and the Upper Midwest. On-site commissioning and remote support both available.
