A.3.2 Operating Modes of the CPU Module
 Operating Modes
There are two operating modes. They can be used to control a user program and all tasks.
STOP mode: A program is not executed under this mode. Users can download a module table, initialize CPU
configuration and other setting, download a program, check a program, and force a bit ON/OFF.
RUN mode: A program is executed under this mode. Users can not download a module table, and initialize CPU
configuration and other setting.
 Statuses and Operation under Different Operating Mode
The STOP mode and the RUN mode are modes for a CPU module. The statuses and operation under these modes are
listed below.
 Basic operation
CPU

Non-
latched
area
Latched
area
STOP
The execution
of the program
stops.
The I/O
refreshing is
executed.
OFF (If users set the I/O module so
that the final state of the external
output on the I/O module is retained,
the final state of the external output
on the I/O module will be retained.)
The data in the program
memories are retained.
RUN
The program is
executed.
The I/O
refreshing is
executed.
The external output is controlled by
the program.
The program memories
are controlled by the
program.
 Relation between the operating modes and the tasks
Mode
Loop task
Interrupt task
STOP
The execution of the loop task stops.
The execution of the interrupt task stops.
RUN
 The tasks which have not been executed are in
the halt state.
 If a task is active, or the instruction TKON is
executed, the task is executed.
 If a task is not active, or the instruction TKOFF is
executed, the task is not executed.
If the condition of the interrupt is met, the
task is executed.
 Relation between the change of the modes and the program memory
Change of the mode
Non-latched area
Latched area
STOP→RUN
Whether the data is cleared or retained depends on user’s
setting.
The data is retained.
RUN→STOP
The data is retained.
The data is retained.
