The relation between the operating mode of the CPU Unit and the mode
switch is as follows:
Key operation Operating

The operating mode of the CPU Unit when the power is turned ON depends
on the status of address 81 in the PLC Setup (Startup Mode) and the connec-
tion status of peripheral devices.

The CPU Unit is stopped. Programming opera-
tions, such as writing or changing programs,
clearing memory, and checking the program,
can be performed.
The CPU Unit is operating and I/O processing
is being performed. In this mode, CPU Unit
operation can be monitored and functions
such as forcing bits ON/OFF, changing timer/
counter SV/PC, changing word data PVs, and
online editing can be used. This mode is often
used for making program adjustments and for
trial system operations.
Used for normal operation of the CPU Unit.
The operating status of the CPU Unit can be
monitored in this mode, but functions such as
forcing bits ON/OFF and changing PVs and
SVs cannot be performed.
