Programming instructions

103
Find Device is used to find a device
address regardless of the instruction.
It will search the entire program for a
particular address. There are a
couple of options on this screen. In
the bottom left you can limit the
search to the entire program, current
location back to top, or current
location to end of program.
There is also a setting for a find
option.
None causes the find function to look specifically for the address entered.
Digit allows the find to look for a bit address in a word of bits. A digit
search of the following code will find that M110 has been used as part of
this TO instruction.
Double Word expands the search to include a word that is used by an
instruction using multiple words. A double word search of the following
code will find that D5 has been used as part of this FROM instruction.
Find Instruction is used to locate all
instances of a particular instruction.
The first dropdown box selects the
ladder symbol and the second
dropdown box selects the command to
search for. The find direction section
works as previously discussed.
Find Step Number
will find a step number in
the program. This can be useful with the error
information previously discussed to search out
the location of a program error in the program.
Find Character String
locates a string of text within the program. If the currently
open window is the ladder logic, it will search for text in the ladder. If the
comment list is open, the comments will be searched, and selection buttons allow
the search to be limited to displayed address list or all addresses, as well as limit
the search to comments or labels.
