Status The following status is displayed depending on the status that is set.
• Normally resolved: Normal data exchange is possible.
• Different sizes: Different sizes are set for the network variables and the
tag settings.

2. The I/O direction that is set in the tag data link settings does not
agree with the I/O direction of the variable in the CPU Unit. There is
an error in the setting of a Network Publish attribute for a CPU Unit
variable.
A connection will not be established for a tag for which this error
occurs.
