SgxEventCapture (FB)

FUNCTION_BLOCK SgxEventCapture EXTENDS AbbLConC3

The ‌“SgxEventCapture” function block detects measurement limit violations AND records(peak value and duration)

Peak value is the maximum or minimum value in 16-bit data format captured in detection cycle

‌Duration represents the event duration captured with 100μs resolution, a value of 0 indicates normal measurement operation

“Application” determines whether the “UpperLimit” and “LowerLimit” are sourced from channel parameters(application = FALSE) or functionblock itself (application = TRUE)

When the digital output is configured as “Event-application FB”, it signals the exceedance OF either “UpperLimit” OR ”LowerLimt”

Event capture triggers on the Enable = TRUE

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. Execution will continue forever until a falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.	AbbLConC3
Output	Busy	BOOL	FALSE	Operation is running (while output Error is FALSE)	AbbLConC3
	Error	BOOL	FALSE	Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.	AbbLConC3
Input	Pause	BOOL	FALSE	0 => Normal operation; 1 => pause the current operation
	Application	BOOL	FALSE	FALSE => Upper/lower limit is active from parameter data; TRUE => Upper/lower paramter is active from this “Function block”
	Lock	BOOL	FALSE	FALSE => continue capture; TRUE => lock the current result not to be overlapped
	EventOutputEnable	BOOL	FALSE	FALSE => mask the digital output not to be activated by event; TRUE => enable the event trigger of digital output
	DigitalOutput	BOOL	FALSE	Imaged digital output field when “general digital output” is configured
	Object	Sgx_WEIGHT_OBJECT	Sgx_WEIGHT_OBJECT.Net	0 => Net; 1 => Gross
	UpperLimit	INT (-1500..1500)	1500	Upper limit to trigger an event when “application” is “TRUE”
	LowerLimit	INT (-1500..1500)	-1500	Lower limit to trigger an event when “application” is “TRUE”
	Channel	POINTER TO SgxChannelIo		Instance of strain gauge channel to be connected
Output	Active	BOOL	FALSE	0 => IndexReturn, PulseWidthReturn and PeakValueReturn are under capture; 1 => IndexReturn, PulseWidthReturn and PeakValueReturn are refreshed
	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code of event detection cycle
	OverRun	BOOL	FALSE	0 => Data read in time; 1 => Data missing (IndexReturn > Previous IndexReturn + 1)
	StateReturn	WORD	0	State of event capture cycle returned,
	IndexReturn	WORD	0	Index of event detected and returned, [0] => digital output state;[1] => ACTIVE; [2] => STATE OF LOCK, [3] = STATE OF EVENT_OUTPUT_ENABLE;[4:7] => Object, 0 = Net, 1 = Gross; [8:9] => fixed unit = 0; [10:11] => diagnosis class; [12:15] => fixed function code = 4
	PulseWidthReturn	WORD	0	Pulse width of event detected and returned, x 100us
	PeakValueReturn	INT	0	Maximum peak value, Max(maximum value - upper limit, lower limit - minimum value)
