FactoryTalk Linx Data Bridge performance reference

Starting from
FactoryTalk Linx Data Bridge
 version 6.20.00, the maximum number of controller tags that can be bridged via
FactoryTalk Linx Data Bridge
 reaches up to 200,000. There are many factors such as the computers' hardware configuration, network loading, and controller communications bandwidth could impact or prevent a system from achieving this high number of tag pairs.
Rockwell Automation
 tests the following scenarios with the test results as a reference.
TIP:
The following data were retrieved from a testing environment. The actual result may be different because of the changes to product firmware, software versions, system or controller network loading. The data was based on
FactoryTalk Linx Data Bridge
 version 6.20.00.
