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
