Operating Modes
PROGRAM Mode
The CPM2C program isn’t executed in PROGRAM mode. Use PROGRAM
mode to create and edit the program, clear memory, or check the program for
errors.
MONITOR Mode
The CPM2C program is executed in MONITOR mode and I/O is processed just
as it is in RUN mode. Use MONITOR mode to test system operations, such as
monitoring CPM2C operating status, force-setting and resetting I/O bits, chang-
ing the SV/PV of timers and counters, changing word data, and online editing.
RUN Mode
This is the CPM2C’s normal operating mode. The CPM2C’s operating status
can be monitored from a Programming Device, but bits can’t be force-set/force-
reset and the SV/PV of timers and counters can’t be changed.
Caution
Check the system thoroughly before changing the operating mode of the PC to
prevent any accidents that might occur when the program is first started.
Caution
Never change the mode while pressing any of the keys.
The operating mode of the CPM2C when the power is turned ON depends upon
the PC Setup settings and the Programming Console’s mode switch setting if a
Programming Console is connected. See
1-3-3 Operating Mode at Startup
for
details.
4-3-4 Preparation for Operation
This section describes the procedures required to begin Programming Console
operation when using the Programming Console for the first time.
Caution
Always confirm that the Programming Console is in PROGRAM mode when
turning ON the PC with a Programming Console connected unless another
mode is desired for a specific purpose. If the Programming Console is in RUN
mode when PC power is turned ON, any program in Program Memory will be
executed, possibly causing a PC-controlled system to begin operation.
