OV4.2 KEY DEFINITION

Keys and key sequences have specific
functions when using the CR10KD keyboard or
a computer/terminal in the remote keyboard
state (Section 5). Table OV4-2 lists these
functions. In some cases, the exact action of a
key depends on the mode the CR10 is in and is
described with the mode in the manual.
TABLE OV4.2-1. Key Description/Editing
Functions
Key Action
0-9 Key numeric entries into display
* Enter Mode (followed by Mode
Number)
A Enter/Advance
B Back up
C Change the sign of a number or
index an input location to loop
counter
D Enter the decimal point
# Clear the rightmost digit keyed into
the display
#A Advance to next instruction in
program table (*1, *2, *3) or to next
Output Array in Final Storage (*7)
#B Back up to previous instruction in
program table or to previous Output
Array in Final Storage
#D Delete entire instruction
#0 (then A or CR) Back up to the start of
the current array.
When using a computer/terminal to communicate
with the CR10 (Telecommunications) there are
some keys available in addition to those found on
the CR10KD. Table OV4.2-2 lists these keys.
TABLE OV4.2-2. Additional Keys Allowed in
Telecommunications
Key Action
- Change Sign, Index (same as C)
CR Enter/advance (same as A)
: Colon (used in setting time)
S or ^S Stops transmission of data (10
second time-out; any character
restarts)
C or ^C Aborts transmission of Data

OV4.3 PROGRAMMING SEQUENCE

In routine applications, the CR10 measures
sensor output signals, processes the
measurements over some time interval and
stores the processed results. A generalized
programming sequence is:
1. Enter the execution interval. In most cases,
the execution interval is determined by the
desired sensor scan rate.
2. Enter the Input/Output instructions required
to measure the sensors.
3. If processing in addition to that provided by
the Output Processing Instructions (step 5)
is required, enter the appropriate
Processing Instructions.
4. Enter the Program Control Instruction to
test the output condition and set the Output
Flag when the condition is met. For
example, use
Instruction 92 to output based on time.
Instruction 86 to output every execution
interval.
Instruction 88 or 89 to output based on a
comparison of values in input locations.
This instruction must precede the Output
Processing Instructions which store data in
Final Storage. Instructions are described in
Sections 9 through 12.
5. Enter the Output Processing Instructions to
store processed data in Final Storage. The
order in which data are stored is
