Introduction to Programming
The cursor will go directly to the first rung from anywhere in user program
by pressing the [SEARCH][↑] keys.
When the [SEARCH][↓] key sequence is pressed, the display will go to the
next boundary in the first section indicated. By pressing the [SEARCH][↓]
key sequence again, a subsequent boundary will be displayed until the user
program end statement is reached.
Boundaries will be displayed at the top of the screen with subsequent
program rungs displayed beneath. No rungs follow the END statement.
Remote Mode Select
The industrial terminal keyboard can be used to change the processor mode
when the keyswitch is in the RUN/PROGRAM position.
The following key sequences can be used:
[SEARCH] 590 for run/program mode
[SEARCH] 591 for remote test mode
[SEARCH] 592 for remote program mode
CAUTION: When using remote program mode or remote test
mode, outputs behave according to the setting of the last state
switch.

Editing
Changes to an existing program can be made through a variety of editing
functions (Table 4.D). Instructions and rungs can be added or deleted;
addresses, data, and bits can be changed.
NOTE: If the memory write protect is active, only data table values
between word addresses 0108 and 3778 can be changed.
