Sheet 02 — The legend
What we work on
Four areas, each a part of the drawing above.
01 / Plant floor
Controls & Automation
Programming, migration, and commissioning for the systems that run the process.
PLC programming
Moving PLC-5, SLC 500, Siemens 505, and older GE systems to current platforms, with AI-assisted code conversion that our team reviews line by line
HMI and SCADA screens
Commissioning and troubleshooting
02 / Security boundary
OT Networks & Security
Networks that keep the plant running and keep outsiders out.
Industrial networks: switches, routers, and firewalls
Segmentation between plant, business, and outside networks
Security assessments and fixes aligned with ISA/IEC 62443
Secure remote access for vendors and staff
03 / Server room
Infrastructure & Recovery
The servers behind your controls, and a way back when they fail.
Servers and virtualization: VMware, Proxmox, and Hyper-V
Active Directory
Backups of controllers, HMIs, and servers, with restores we actually test
04 / Signal path
Industrial Data & AI
Getting data out of the plant safely, and making it useful.
Historians and data collection over OPC UA, MQTT, and SQL
Downtime, OEE, and scrap data turned into fixes, not just dashboards
AI that reads your plant and never drives it
