With this command you search for a certain passage just as with the command 'Edit' 'Find', and replace it with another⮫ “'Edit' 'Find'”. After you have chosen the command the dialog box for find and replace appears. This dialog box remains open until the button 'Cancel' or 'Close' is pressed.

In the field behind 'Find' automatically that string will be inserted which you have marked before in the editor. You also can enter the search string manually. Pressing button 'Replace' will replace the current selection with the string which is given in the field 'Replace with'. Use the button 'Find Next' to get to the next passage where the string is found. Please regard, that FBD POUs are processed from the right to the left!

The button 'Replace all' replaces every occurrence of the text in the field 'Find next' after the current position with the text in the field 'Replace with'. At the end of the procedure a message announces how many replacements were made.
