Principles of Operation
The FactoryTalk Live Data (FTLD) Interface is a FactoryTalk Live
Data client that enables process data to be passed between a
FactoryTalk Live Data server (for example, RSLinx Enterprise) and
a FactoryTalk Historian server. Each instance of the FTLD Interface
can provide data to a single FactoryTalk Historian SE server or
collective. Multiple instances of the interface may be configured, if
required, if API buffering is used.
The figure below shows the basic workflow of the FactoryTalk
Historian Live Data Interface.
