Programming Console Operations
Appendix D

Operation/Description
Key sequence
Modes*
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 pro-
gram is being executed. Increment-
ing and decrementing can only be
carried out if the SV has been entered
as a constant.

3-word Change
This operation changes the value of a
word displayed during a 3-word
monitor operation. The blinking
cursor indicates the word that will be
affected by the operation. The cursor
can be moved by using the up and
down keys. When the cursor is at the
desired location, press CHG. After
entering the new data, pressing
WRITE causes the original data to be
overwritten.

Scan Time Display
This operation should be performed
after all syntax errors have been
corrected. The scan time can only be
checked in RUN or MONITOR mode
and while the program is being
executed. The scan time displayed
after pressing CLR and MONTR is
that for the current scan. Pressing
MONTR again will display a new scan
time. The difference between the
displayed scan times is due to the
different execution conditions that
exist during each scan.

Hex-ASCII Display Change
Converts 4-digit hexadecimal DM
data to ASCII and vice-versa.
