Basic Instructions
Description
When the NSTL instruction or the NSTP instruction is executed, the process starting with the SSTP
instruction of the specified number is started and executed.
In a step ladder program, a process is identified as being from one SSTP instruction to the next SSTP or
STPE instruction.
Example:
Operations such as the sequence control, selection branch control, parallel branch control are easily
executed.
− Sequence control
Only the necessary processes are switched and executed in order.
Process 1 Process 2
− Selection branch control
The processes are selected and executed according to conditions.
Process 1
− Parallel branch merge control
Multiple processes are executed simultaneously.
After each process is completed, the next process is executed.
