7–3–2 PC Modes
The Programming Console is equipped with a switch to control the PC mode.
To select one of three operating modes—RUN, MONITOR, or PROGRAM—
use the mode switch. The mode that you select will determine PC operation
as well as the procedures that are possible from the Programming Console.
RUN mode is the mode used for normal program execution. When the switch
is set to RUN and the START input on the CPU Power Supply Unit is ON, the
CPU will begin executing the program according to the program written in its
Program Memory. Although monitoring PC operation from the Programming
Console is possible in RUN mode, no data in any of the memory areas can
be input or changed.
