The use of Siemens TIA Portal offers numerous benefits for PLC and HMI development, including: plc and hmi development with siemens tia portal pdf
Most official Siemens PDF manuals or third-party textbooks on this topic follow a logical, layered progression: Before writing a single line of code, you
IF "Start_Timer" THEN "Timer_DB".TON(IN := TRUE, PT := T#5s); IF "Timer_DB".Q THEN "Output" := TRUE; END_IF; ELSE "Timer_DB".TON(IN := FALSE); "Output" := FALSE; END_IF; PT := T#5s)
The Main [OB1] is where your program executes cyclically.
