Troubleshooting The Control

For example, your PAL program consists of three foreground modules and
two background modules. You are currently in the second foreground
module and you want to search for the symbol $ESTOP only in
foreground. You enter the symbol $ESTOP as the symbol search type and
press {FORWRD SEARCH}. This searches the rest of the second
foreground module and the third foreground module. If it is not found in
that direction when the utility reaches the first background module it
prompts, SEARCH BACKGROUND MODULES (Y/N). Answering NO
aborts the search and leaves the cursor at the original starting position.
The search string is still in memory. Select {REVRSE SEARCH}. This
searches the second foreground module from the cursor to the beginning of
the module and the first foreground module. If the search string is still not
found, the OBJECT NOT FOUND IN PROGRAM message appears and
the search string does not exist in any foreground modules.
The five different types of searches are as follows:
(softkey level5)
SELECT
SYMBOL
SELECT
ELEMNT
SELECT
OPERTR
SELECT
RUNG
SELECT
MODULE
Select Rung
Use this search type when you know the rung number that you want to
monitor. When you press the {SELECT RUNG} softkey, the control will
prompt you to enter a rung number. Enter a rung number between 1 and
9999 and press transmit (wild cards are not permitted with this search
type). If it does not find the rung number in the current module, the
message RUNG NUMBER DOES NOT EXIST is displayed. The search
monitor utility will only attempt to find this rung number in the currently
selected module. To search other modules you must change the active
module using the Select Module option, or cursor keys.
Select Operator
Use this search when you need to search the PAL program for a specific
operator (such as a GTO or TON). Refer to your PAL reference manual
for details on these specific operators. To select an operator search press
the {SELECT OPERTR} softkey. The search monitor utility displays a
listing of the available operators. Use the cursor keys to select an operator
and press transmit. Then select the direction you wish to search in using
the {FORWRD SEARCH} or {REVRSE SEARCH} softkeys.
Select Symbol
Use this search when you need to search the PAL program for a specific
symbol. This search operation allows the use of one wildcard
character (*). Select the symbol search by pressing the {SELECT
SYMBOL} softkey. The control will prompt you to enter a symbol. Enter
that symbol name and press transmit. Then select the direction you wish to
