command in the Step
Ladder Program, or the
method of use of
commands is wrong, for
example, there is an AND
command even though
there is no input command.
Either the function block is
not registered to the block
address currently specified
by each command in the
Step Ladder Program, or
the ITEM number does not
exist.
The number of
differentiated instructions
to be simultaneously
executed has exceeded
256.
If using a Controller Link connection, you can display the Controller Link Net-
work's data link status.
Click the DTL Button.
The Data Link Status Dialog Box will be displayed.
