Changing the program execution type
The execution type of programs can be changed using instructions even during execution. Use the PSCAN, PSTOP, or
POFF instruction to change a program execution type.
Once the fixed scan execution type program is changed to another execution type, the type cannot be returned to the fixed
scan execution type.
