Determine import order

If you are importing from more than one InTouch node, the following scenarios can exist:

• You have more than one InTouch node retrieving values from the same I/O tag, which is receiving values from the same point on a factory device.

• You have an InTouch node retrieving values from an I/O tag on another InTouch node, which is receiving its data value from a point on a factory device.

• All of your InTouch nodes are retrieving values from I/O tags on a dedicated InTouch node, which is receiving its data values from a point on a factory device. In this case, the dedicated InTouch node is set up to function as a "tag server."

When you import tagname dictionaries from multiple InTouch nodes, avoid importing duplicate I/O tags. To maximize the efficiency of importing data, first import the InTouch node that is functioning as the tag server or that contains the highest number of tags that have direct access to the data points from the factory floor devices.

As you import multiple nodes, always import a node with more tags having direct access, before importing a node having fewer tags with direct access.
