(3) Processing of file register's block numbers
(a) When switching from the scan execution type/low-speed execution type program to
the interrupt/fixed scan execution type program
The CPU module saves the file register block numbers in the scan execution type/low-speed execution type
program, and passes them to the interrupt/fixed scan execution type program.
(b) When switching from the interrupt/fixed scan execution type program to the scan
execution type/low-speed execution type program
The CPU module restores the saved block numbers of the file register.
