Automation & controls
PLC programming for Houston and the Gulf Coast
Control systems only work when the sequence of operations is explicit and the program matches the equipment in front of you. Good Day Source programs PLCs and HMIs for Gulf Coast facilities, Allen-Bradley/Rockwell and Siemens, including interlocks and alarm management.
The work is scoped on the equipment, tested before it is put on the running plant, and left with records a technician can use later.
Who it is for
Refining and petrochemical units, midstream stations, upstream production sites, power generation, motor shops that need a controls package with a rebuild, and EPC or electrical/I&C contractors who want programming and documentation from one team.
Capabilities
PLC programming
Allen-Bradley/Rockwell and Siemens programs written to a defined sequence of operations.
HMI development
Operator screens that show the state of the equipment without a second system to interpret.
Control logic and interlocks
Permissives and interlocks written down and implemented so startup has a known order.
Alarm management
Alarms that mean something: what tripped, what to check, and what is only noise.
Typical deliverables
- Sequence of operations
- PLC and HMI files
- Interlock and alarm list
- Startup notes for the unit

- 02
Build & simulate
Program and test before it touches the field.
- 03
Commission & document
Startup, settings, and records for every unit.
- 04
