PLC & HMI Programming

PLC and HMI work is our core. We help plants evolve existing systems, add new equipment and keep software maintainable over the long term.

Siemens

S7-300/400/1200/1500, TIA Portal, legacy Step 7, Profibus/Profinet.

ControlLogix/CompactLogix, Studio 5000/RSLogix, EtherNet/IP.

TwinCAT 3, EtherCAT; CoDeSys-based OEM controllers.

NJ/NX series; safety and motion integration.

Modular, commented code with clear diagnostics to make fault-finding quicker on nights and weekends.

Fieldbuses, safety I/O, drives and higher-level systems as needed.

We design HMIs and SCADA views that make it easy for operators and maintenance to see what matters.

We focus on alarm management, clear navigation, historian hooks and giving maintenance enough detail to diagnose issues quickly.

For sites that need history and KPIs, we build on-prem dashboards using secure, open-source stacks with full data ownership and no heavy licensing.

We understand both the control code and the network it runs on — from control panels to OT switches and VPNs.
