Operation/Description Key sequenceModes*
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.

Binary Data Change
This operation is used to
change the value of 16-bit IR,
HR, AR, LR, or DM words
bit-by-bit. The cursor can be
moved left by using the up key,
and right using the down key.
The position of the cursor is the
bit that will be overwritten.
There are two types of
changes, tem-porary and
permanent. Temporary changes
result if 1 or 0 is entered.
Permanent changes are made
by pressing SHIFT and SET, or
SHIFT and RESET. (These are
only avail-able on the C200H
PC.) The former will result in an
S being displayed in that bit
position. Similarly, SHIFT and
RESET will produce an R in the
dis-play.
During operation of the PC, the
bits having 1 or 0 values will
change according to the
conditions. Bits with S or R will,
however, always be treated as
a 1 or 0, respectively. NOT
cancels S and R settings and
the bits will become 1 or 0,
respectively.
Pressing WRITE transfers the
changes made on the display to
the memory.

SV Change,

There are two ways of
modifying the SVs for timers
and counters. One method is to
enter a new value. The other is
to increment or decrement the
existing SV. In MONITOR mode
the SV can be changed while
the program is being executed.
Incrementing and decrementing
can only be carried out if the SV
has been entered as a
constant.
