Y_PK_UN_EventSummation

The UN_EventSummation function block summarizes all EM events to create a single listing of all active Events in the machine. All events are added to the Event History FIFO (max 50 events), typically stored in a retained variable.

Parameters

*	Parameter	Data Type	Description	Default
VAR_IN_OUT
V	Inp_UNEventStatus	Yt_PK_UN_EventSummation_STRUCT	A variable that contains all the active event information for a machine
V	Inp_EventHistory	Yt_PK_EventHistoryArray	FIFO to store information on the last 50 events
V	EventList	Yt_PK_EventCfgArray	Structure containing defined events
VAR_INPUT
B	Enable	BOOL	The function will continue to execute while the enable is held high	FALSE
V	Cmd_Reset	BOOL	Clears the entire list of events except for the FirstOutEvent	FALSE
V	Cmd_ResetFirstOut Events	BOOL	Clears only the FirstOutEvent. Note that both inputs must be set to clear all events completely	FALSE
V	Cmd_ResetEventHistory	BOOL	Clears the Event History FIFO	FALSE
V	Inp_FirstOutcategories	WORD	Determines which categories are designated to capture the first Out Event.	16#FFFE
VAR_OUTPUT
B	Valid	BOOL	Indicates that the outputs of the function are valid
B	Sts_EventActive	BOOL	Indicates if an event has occurred and been collected
B	Sts_NumActiveEvents	INT	A summary count of all currently active events on the machine
V	Sts_FirstOutEvent	Yt_PK_Event_STRUCT	The event that occurred first on the machine
V	Sts_ActiveList	Yt_PK_UN_AllEventArray	Active list of events
V	Sts_MostSevereCategory	DINT	A list of the most severe categories
B	Sts_ActiveCategories	DWORD	A combination of all the individual event categories. Each event Category is OR’d to create a single indicator of event severity
B	Error	BOOL	Set high if error has occurred during the execution of the function block. This output is cleared when 'Execute' or 'Enable' goes low.
B	ErrorID	UINT	If Error is true, this output provides the Error ID. This output is reset when 'Execute' or 'Enable' goes low.
