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.
