SECTION 1. FUNCTIONAL MODES
1-3
multiplier and offset can be entered in
4
locations 1 and 2, respectively.
A
4
location can be used in only one
program parameter. For example,
4
locations 0, 1, and 2 used in the example
cannot be reused in another instruction in the
same program.
If the 4 feature is enabled in EDLOG
when printing a program to a printer or disk file,
the
4 list is printed at the end of the file.
Once the EDLOG created program has been
sent to the CR23X, it can be saved in the Flash
memory program storage area using the
D Mode (Section 1.8).
CHANGING VALUES IN
4
TABLE
Enter the
4
Mode by keying "
4
";
"04:00" is then displayed. At this point it is
possible to jump to any valid
4
location by
keying the desired location number and
pressing the A key. For example, when the
display shows 04:00 and the desired location is
80, key in the number 80, press the A key and
the display will show "80:XXXXX." where
XXXXX. is the value stored in location 80.
Pressing the "A" key advances to the next
4
location, and the "B" key backs up to
the previous location. If a
4
location is not
assigned in the datalogger program, it can not
be displayed in the
4
mode.
To enter a value in a
4
location, advance
to the desired location, key in the number and
enter it by pressing the "A" key. The value is
not entered if the "A" key is not pressed.
Entering a new value causes the datalogger to
stop logging. Logging resumes when the
program is compiled. Upon compiling (
0
or 6 ), all current 4 values are
incorporated into the program. For this reason,
whenever changes are made in the
4
mode, make sure that all 4 values are
correct before exiting the 4 mode.
Removing or adding an instruction to a program
residing in the datalogger disables the
4
mode. An instruction parameter may be edited
without any adverse affect. If the
4
mode
is disabled, it may be reactivated by
downloading the program to the datalogger or, if
the program was saved to Flash storage,
retrieving the program from the stored program
area.
The
C
mode (Section 1.7) may be used to
secure the datalogger program and the 4
mode entries. The lowest level of security
prevents access to the
1 , 2 , and
3 modes. Higher levels of security block
4 .
The CR23X will not respond to the 4
command if any of the following conditions
exist.
•
the program that was downloaded does not
contain any
4
assignments.
•
a program that was downloaded has since
been hand edited.
•
Security is blocking access to
4
.
1.1.5 COMPILING A PROGRAM
When a program is first loaded, or if any
changes are made in the
1 , 2 ,
3 ,
4
,
A
, or
C
Modes, the
program must be compiled before it starts
running. The compile function checks for
programming errors and optimizes program
information for use during program execution. If
errors are detected, the appropriate error codes
are indicated on the display (Section 3.10). The
compile function is executed when the
0
,
6
, or B Modes are entered and prior
to saving a program listing in the D Mode.
The compile function is only executed after a
program change has been made and any
subsequent use of any of these modes will
return to the mode without recompiling.
When the 0 or
B
Mode is used to
compile, all output ports and flags are set low,
the timer is reset, and data values contained in
Input and Intermediate Storage are reset to
zero.
When
0 is used, one of the following
status lines will be displayed: Running Table 1,
Running Table 2, No Active Program, Running
Table 1, 2, Tables Not Running.
When the 6 Mode is used to compile data
values contained in Input Storage, the state of
flags, control ports, and the timer (Instruction
26) are unaltered. Compiling always zeros
Intermediate Storage.
