String instructions

FIND returns the position at which the second input string first occurs in the first input string. The

result is written into the output variable. If the second input string does not occur in the first input

string, the value ZERO is returned.

To add an enable input and enable output to the instruction, select [With EN/ENO] from the

"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the

context menu or press <Ctrl>+<Shift>+<v> in the programming window.

Availability of FIND (see page 1326)

 If the strings are longer than the length defined for the input variables

(input_string_1 and input_string_2) in the field "Type", an error occurs

(see Special Internal Relays for Error Handling).

 The number of steps may vary depending on the PLC and parameters

used, see also Table of Code Intensive Instructions in the online help.

(up to 200 steps)

In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

All input and output variables used for programming this function have been declared in the POU

In this example the input variables (input_string_1 and input_string_2) have been declared.

Instead, you may enter the strings ('Ideas for life' and 'for') directly into the function. The strings

have to be put in inverted commas, both in the POU header and in the function.

Input_string_2 ('for') is searched in input_string_1 ('Ideas for life'). The position of the first

occurrence (7) is written into output_value.
