PLC Programming
New control logic and revisions to existing programs, written to be readable by the next person who opens it.
- Ladder, structured text, and function block routines
- Tag structures, UDTs, and add-on instructions
- PID and sequence control for process equipment
- Alarm, permissive, and shutdown logic
- Program revisions with tracked change notes
- Commented code and archived program backups

HMI & SCADA Development
Operator screens built around how the equipment actually runs, so the information people need is on the screen they are already looking at.
- Screen layout, navigation, and faceplate development
- Alarm and event configuration with priority tiers
- Trending, historical data, and runtime displays
- User roles, screen security, and access levels
- Tag mapping between controller and display
- Panel-mount and remote client deployment
Controls Integration
Getting mixed-vendor equipment, meters, and skids talking to one control system and reporting the same numbers.
- Controller-to-device communication setup
- Protocol conversion through gateways
- Third-party skid and packaged equipment integration
- Flow computer and meter data mapping
- Network layout, addressing, and register maps
- Data delivery to host and SCADA systems
Commissioning & Startup
Point-by-point verification before equipment runs, and on-site support through the first days of operation.
- I/O checkout and loop verification
- Instrument range and calibration confirmation
- Functional testing against the control narrative
- Valve stroking and response checks
- Sequence and interlock dry runs
- Startup support and punch list closeout
Automation Troubleshooting
Finding the actual cause of a control problem, including the intermittent ones that clear before anyone gets to site.
- Communication faults and dropped devices
- Intermittent I/O and wiring-related failures
- Unstable control loops and tuning issues
- Nuisance alarm and unexplained shutdown review
- Undocumented legacy program analysis
- Written findings and corrective action notes
Control System Modernization
Moving obsolete or unsupported control systems forward while keeping the facility running.
- Migration from obsolete controller platforms
- Legacy program conversion and rewrite
- Hardware replacement planning and spares review
- Instrument and measurement technology upgrades
- Cutover sequencing to limit downtime
- Updated as-built and configuration records
