5. Press [ENTER] to locate the instruction. Since this is an output energize
instruction, there should be only one occurrence of this instruction and
address. For other types of instructions, such as the examine if closed
(XIC) instructions that you saw earlier, pressing
[ENTER] , finds each
additional occurrence of the instruction with that address.
Reversing the Search Direction
The default setting for the search direction is to search from the cursor
position down to the end of the program, then wrap around to the start of the
program. In a large ladder program, you may want to change the search
direction.
Each time you bring up the search display, the direction function displays UP :
] [ ] [
2.0.0.0.*
F1 F2 F3 F4 F5
] [ ( )
] [
] [ ( )
( )
] [ ] [ ] [
] [ ( ) ] [
] [ ( ) ] [ ] [ ] [
CUR–INS CUR–OPD NEW–INS FORCE UP
OFL +
With UP displayed, the search starts at the cursor location, in this case at the
start of the program, and continues toward the end of the program.
