Monitoring and Data Changing Operations
Operation/Description
Bit/Word Monitor
Up to six memory addresses,
containing either words or bits, or a
combination of the two, can be
monitored at once. Only three can
be displayed at any one time. If
operated in RUN or MONITOR
mode, the status of monitored bits
will also be displayed.
The operation can be started from a
cleared display by entering the
address of the first word or bit to be
monitored and pressing MONTR, or
from any address in the program by
displaying the address of the bit or
word to be monitored and pressing
MONTR.
When a timer or counter is
monitored, its PV will be displayed
and a box is displayed in the bottom
left hand corner if the Completion
Flag is ON.
Applicable data areas vary
according to the PC being used.
Forced Set/Reset
If a bit, timer, or counter address is
leftmost on the screen during a
Bit/Word Monitor operation,
pressing PLAY/SET will turn ON the
bit, start the timer, or increment the
counter. Pressing REC/RESET will
turn OFF the bit, or reset the timer
or counter. These force-sets and
force-resets are effective for one
cycle.
Timers will not operate in
PROGRAM mode. SR bits are not
affected by this operation.
Hex/BCD Data Change
Used to edit the leftmost BCD or
hexadecimal value displayed during
a Bit/Word Monitor operation. If a
timer or counter is leftmost on the
display, the PV will be the value
displayed and affected by this
operation. It can only be changed in
MONITOR mode and only while the
timer or counter is operating. SR
words cannot be changed using this
operation.
