Modern PLC projects suffer when control logic is scattered across rungs, hidden in timer branches, or tightly coupled to raw I/O. The result is brittle behavior, difficult commissioning, and painful offline testing.

It divides each routine into clear sections—Inputs → Commands → Interlocks → Permissives → State & Transitions → Status → Control Resources → Outputs—and enforces one rule above all: states govern state; device control happens only in Outputs. Whether you write in ST or Ladder, this structure keeps behavior predictable and easy to review. ...

CSV Files CSV Files are a handy way to pass data around. A lot of programs can import/export CSV file for you to easily edit in excel and save some time. Sometimes you want to parse through and maybe generate CSV files to use as well. Let’s read a CSV file in golang. Open a CSV file fi, err := os.Open("path-to-csv.csv") if err != nil { log.Fatal(err) } defer fi.Close() Initialize our reader rdr := csv.NewReader(fi) Once we set up our reader, when we want the next row, we call row, err := csv.Read() ...
