SECTION 1. FUNCTIONAL MODES
1-3
TABLE 1.3-1. *6 Mode Commands
Key Action
A Advance to next location or enter
new value
B Back-up to previous location
C Change value in displayed
location(Key C, then value, then A)
D Display/alter user flags
# Display current location and allow a
location no. to be keyed in, followed
by A to jump to that location
* Exit *6 Mode
1.3.1 DISPLAYING AND ALTERING INPUT
STORAGE
When *6 is keyed, the display will read
"06:0000". One can advance to view the value
stored in Input Storage location 1 by pressing A.
To go directly to a specific location, key in the
location number before keying A. For example,
to view the value contained in Input Storage
location 20, key in *6 20 A. The ID portion of
the display shows the last 2 digits of the location
number. If the value stored in the location being
monitored is the result of a program instruction,
the value will be updated each time the
instruction is executed.
Values may be entered into input locations using
the change command, C. While viewing the
contents of the input location in which the value
is to be entered, key C; the location number in
the ID field will disappear. Key in the desired
value and then enter it by pressing A.
If an algorithm requires parameters to be
manually modified during execution of the
program WITHOUT INTERRUPTION of the
Table execution process, the parameters can be
loaded in Input Storage locations and the *6
Mode can be used to change the values. If
values must be in place before program
execution commences, use Instruction 91 at the
beginning of the program table to prevent
execution until a flag is set high (see next
section). The initial values can be entered into
input locations using the *6 Mode after compiling
the table. The flag can then be set high to
enable the table(s).
If any program tables *1, *2, *3, or *4 output
options are altered and complied in the *0
Mode, values in Input Storage will be set to 0.
To preserve values entered in Input Storage,
compile with *6.
1.3.2 DISPLAYING AND TOGGLING USER
FLAGS
If D is keyed while the 21X is displaying a
location value, the current status of the user
flags will be displayed in the following format:
"00:01:00:10". The characters represent the
flags, the left-most digit represents Flag 1 and
right most Flag 8. A "0" indicates the flag is low
and a "1" indicates the flag is high. In the above
example, Flags 4 and 7 are set high. To toggle
a flag, simply key the corresponding number.
To return to displaying the input location, press
A.
Entering appropriate flag tests into the program
allows manual control of program execution.
For example: It is desired to be able to
manually start the execution of Table 2.
Instruction 91 is the first instruction entered in
Table 2:
01: P91 If Flag
01: 25 5 is set low
02: 0 Go to end of program table
If Flag 5 is low, all subsequent instructions in
Table 2 will be skipped. Flag 5 can be toggled
from the *6 Mode, effectively starting and
stopping the execution of Table 2.
1.3.3 DISPLAYING AND TOGGLING PORTS
The current status of the user's ports can be
displayed by hitting "0" while looking at an input
location (e.g., *6A0). Ports are displayed left to
right as 0, 0, C6, C5, ..., C1 (exactly opposite to
the flags). A port can be toggled by pressing its
number on the keypad while in the port display
mode.
1.4 COMPILING AND LOGGING DATA -
*0 MODE
When the *0 Mode is entered after programming
the 21X, the program is compiled (Section 1.1.4)
and the display shows "LOG" and the numbers
of the program tables that were enabled at
