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.
