C USTOM E VENTS - A NALOG
The FTMLE_Workcell UDT contains a UDT called FTMLE_AnalogEvents — an array
of one Boolean value and one Integer value. The UDT field called Events_Analog
consists of an array of five occurrences of the FTMLE_AnalogEvents UDT.
The five
triggers are interpreted by FactoryTalk Metrics as triggers for five analog events. The five
integers are interpreted as event values. Typically, reason codes for the event are provided
by the operator or control system. Each of these trigger/value pairs are independent and
should indicate that an important workcell event is occurring that FactoryTalk Metrics
should track. The trigger value should change from 0 to 1 (or low to high) when the event
to track is occurring, and should change back to 0 (or low) when the event ends. The
control system should copy an event value to the Value data point before the event ends
and the trigger returns to low. Each trigger/value pair should indicate only one distinct
event that may have multiple causes (for example, downtown operator stop, etc.). Once
these events are configured in FactoryTalk Metrics by the FactoryTalk Metrics
Configuration tool, you should edit the performance parameters to give them meaningful
names and to provide lookup lists to translate the integer values returned in the value data
points to string values for reporting. See “Modifying performance parameters” on
page 45.
