Ladder Programming with Tag Data Links

Section 6-3

Programming for Revision 2 or Higher

Programming for Revision 1 and Revision 2

Programming to Detect
Errors: Example 1

The following programming can be used to check for errors for each target
node. This programming is used to detect errors only after the data links for all
nodes have started normally.

Programming for Revision 2 or Higher

Programming to Detect
Errors: Example 2

The following programming can be used to detect tag data link errors at the
local node.
