With DOWN displayed, the search starts at the cursor location, in this case at
the start of the program, wraps around to the end of the program and
continues toward the start of the program.
Whenever you exit the search function, the direction display defaults back to
UP .
Searching for Forced I/O
Searching for forced I/O is most useful in the Online Monitor mode, but can
be used in the Offline Editing mode after a ladder program has been running
in a processor and uploaded to the HHT. Refer to chapter 10 for details
regarding uploading a ladder program and chapter 13 for a detailed
description of the force function.
In the Online Monitor mode, use the search forced I/O function to locate all
forced inputs and outputs that are inserted in your program.
In the Offline monitor mode, use the search forced I/O function to locate all
forced inputs and outputs that were inserted into your program the last time it
was operating in the Run mode before being uploaded to the HHT. Then
document the location of each force and investigate the effects on machine
operation before downloading the modified program.
!
ATTENTION: Use the search force function to locate all forces
that have been uploaded to the HHT. Downloading a program
containing forces can cause personal injury and damage to
equipment.
