material, or equipment changes occur.
Distributed FactoryTalk Historian
Architecture
Data or process historians are software applications that log data from process
equipment, manufacturing devices, and other main data sources that are important
and relevant for the overall manufacturing process and for product quality. The
FactoryTalk Historian collects time series data, which is very different from
traditional relational data and event data. The FactoryTalk Historian collects data
points at given intervals whether or not the data points are changing. This allows
customers to see how these data points are trending, and allows them to look at
correlations of data points.
Because the FactoryTalk Historian continuously collects data, it allows customers to
review past data and view what occurred at a specific past point(s) in time. This
means that if a specific event such as a downtime event, a bad batch, or an alarm
occurs, an operator can look at any process variable in the FactoryTalk Historian for
the same time frame as the event, and search for correlations that might explain the
event. This allows the user to improve production and operational processes,
eliminating the anomaly in the future.
The FactoryTalk Historian distributed architecture is multi-tiered. It redefines
available options for manufacturers who want to maximize their ability to collect and
analyze process data. It introduces a scalable, modular, synchronized methodology
for collecting, maintaining, and analyzing process data at each level of manufacturing
operations - machine or line, plant and enterprise (multi-plant). Specifically, the
