PLC programming
The layer that runs the process: sequence logic, interlocks, alarm handling and I/O.
Programs written to be read as well as run — structured, commented and handed over, so the next engineer on site isn't reverse-engineering somebody else's shorthand at two in the morning. New logic from scratch, or changes to a machine that has already been through three sets of hands.
- Sequence and batch logic
- Interlocks and safety permissives
- Alarm handling
- I/O configuration
