Chapter 3 Collecting Performance Data
• Overall Available
An Overall Available event record is created for each workcell
for each continuous period of Overall Availability. Overall
Availability takes into account all of the applicable availability
factors that may determine if a workcell is available: schedule,
schedule unavailable time, availability data point, and activity
area exception unavailable time. The time spent in an Overall
Available status is also captured in the Available Seconds field
of the FactoryTalk Metrics Workcell History report data
source.
• Activity Area Exception Unavailable
An event record will be created for every continuous period of
time that a workcell experiences Exception Unavailable Time.
• Activity Area Available - Point
An event record will be created for every continuous period of
time that a workcell is available as defined by an activity area
Availability data point, which is specified in the Availability
section of the Performance Parameter screen. A record will be
created every time the Availability point in the control system
goes high, and closed when it goes low. If an Availability
formula is used, there will be an event created for each
component of the formula.
• Running - Point
An event record will be created for every continuous period of
time that a workcell is Running as defined by a Running data
point, which is specified in the Running section of the
Performance Parameter screen. A record will be created every
time the Running point in the control system goes high, and
closed when it goes low. If a Running formula is used, there
will be an event created for each component of the formula.
• Activity Area Part Count - Formula
This system-level event is created when a part count formula is
used in a workcell. An event record is created when data
