1) Example of changing the execution type in scan execution type program
• Set programs "ABC" and "GHI" as scan execution type programs.
Set program "DEF" as a stand-by type program.
• When the condition is satisfied (the internal relay (M0) in Diagram 3.40
turns ON), "DEF" is changed into a scan execution type program and
"ABC" into a stand-by type program.
Scan execution type program: ABC
M0

PSTOP "ABC"
Stand-by type program: DEF
PSCAN
PSTOP "DEF"
Stand-by type program: ABC
