The support your systems demand.
We design, program and commission the control systems that run production — PLC logic, HMI screens, SCADA architecture and the field instrumentation feeding them. The panel below is a working example. Start a pump and watch the loop respond.

What we build
Fifteen years of field-tested work across production, midstream and water handling. We take the system from concept through startup and stay reachable after handoff.
PLC programming
Ground-up programs and modifications to existing code. Structured, documented and written so the next person can read it.
HMI development
Screens built around how the operator actually runs the unit — clear states, meaningful alarms, no guessing at what a color means.
SCADA architecture
Tag databases, polling, historians and reporting. Designed to scale as you add sites instead of being rebuilt every time.
Instrumentation
Transmitter and analyzer setup, loop checks, calibration and signal troubleshooting from the sensor to the controller.
Control panels
Panel layout, I/O and network drawings, and coordination with the build so what shows up on site matches the print.
Startup & commissioning
Point-to-point checkout, functional testing and on-site support through first production. Documentation included.
Where these systems run
Four sectors, one discipline. Hover a sector to see what we are typically asked to control.
- Tank batteries
- Saltwater disposal
- LACT & flow measurement
- Vapor recovery
- Crusher circuits
- Belt scales
- Wash plants
- Conveyor sequencing
- Packaging lines
- Palletizing cells
- Batching & recipes
- Downtime reporting
- Lift stations
- Chemical feed
- Blower control
- Telemetry & polling
Five steps, in order
The same sequence on every job, whether it's a two-day modification or a full skid.
Scope
We walk the process with you, review existing drawings and code, and put the deliverables in writing before anyone quotes a number.
Design
Control narrative, I/O list and architecture. You approve the approach before development starts, so there are no surprises at FAT.
Develop
Logic and screens built and simulated off-site. Testing happens in the office, not on your production time.
Commission
On-site checkout, loop verification and startup support until the system runs the way the narrative says it will.
Support
Documented turnover package, and a phone number that gets answered when something changes six months later.
