When you are monitoring a file, the location of the cursor in the ladder
program determines how you access a particular address within a data file:
•
If the cursor is on an instruction when you press [ F3 ], EDT_DAT, the
cursor moves to the address (bit or word level) of the instruction in the
appropriate data file.
•
If the cursor is on a power rail or branch intersection when you press [ F3 ],
EDT_DAT, the cursor moves to the beginning of the first data file, the
Output data file. You can then use the ADDRESS function key, followed
by [
ENTER ] to specify any address in the data table.
Monitor the counter data file by pressing [ F3 ], EDT_DAT. The following
display appears:
