recorded in advance and the specified program file must exist on the Memory
Card in order to replace the program during operation.
The program can also be replaced when program execution is stopped (PRO-
GRAM mode) by turning ON the Replacement Start Bit from a Programming
Device.
Note The replacement program file cannot be read from EM file memory.
The Replacement Start Bit (A65015) can be turned ON at any location (pro-
gram address) in the program. The CPU Unit will execute the instructions
remaining in the cycle after the Replacement Start Bit goes from OFF to ON.
The program will not be executed while the program is being replaced. After
the program has been replaced, operation will be started again just as if the
CPU Unit were switched from PROGRAM mode to RUN or MONITOR mode.
The program will be replaced at the end of the cycle in which the Replace-
ment Start Bit was turned from OFF to ON, i.e., after END(001) is executed in
the last task in the program.
