LogGeneric_Input (FB)

FUNCTION_BLOCK LogGeneric_Input EXTENDS AbbLConCA

This function at the same time, can write Datasets of type BOOL, BYTE, INT, UINT, DINT, UDINT and REAL with different length of 27…88 values (depending on type) are stored as Format *.csv in SRAM-FIFOin of Data logger

The Function Block writes datasets in the SRAM-FIFOin of the controller and doesn’t send them directly to a central control station. This is done by the user. With the Function Block LogGeneric_Output the data to be sent are provided as an interface.

InOut:

Scope	Name	Type	Initial	Comment
Input	Send	BOOL		2: Start a send request on raising edge
	Cycle	BOOL		3: Perform a cyclic send each scandown cycle. At Scandown=0 a dataset is written in each cycle
	Auto	BOOL		4: With each change of an input value or exceeding/falling down of Threshold, this input writes a dataset in FIFOin
	Scandown	UINT		5: On cyclic send only send in each <scandown< cycle e.g. Scandown = 100: every hundredth cycle writes a value in FifoIn e.g. Scandown = 0: in every cycle a dataset is written
	ThresholdRefresh	BOOL		6: Threshold refresh. FALSE: refresh each thresholds separately. TRUE: refresh all thresholds together when one threshold reached
	Id	STRING(8)		7: Sender Identity - maximum 8 character, freely selectable name/text
	DataType	BYTE		8: Possible Data types: 1=BOOL, 2=BYTE, 3=INT, 4=UINT, 5=DINT, 6=UDINT, 7=REAL
	Length	INT		9: Current length of Data. Maximum value 88
	Threshold	POINTER TO DINT		10: When exceeding or falling below a threshold, a writing operation of a dataset into the FIFOin is started. After this operation, either only the single threshold difference (between input and threshold) is deleted (ThresholdRefresh=FALSE) or all differences (ThresholdRefresh=TRUE). As the input is a poiner to, it has to be connected to an preceding ADR-Operator, to which any available input type can be provided: BOOL, BYTE, INT, UINT, DINT, UDINT, REAL or an array of these data types. Make sure that Threshold is always of the same type as the respective input E.g. if the Input is an ARRAY[0..n] OF BYTE, Threshold has to be an ARRAY[0..n] OF BYTE too. This input is only relevant for 2=BYTE, 3=INT, 4=UINT, 5=DINT, 6=UDINT, 7=REAL, not for bool. For the BOOL type inputs, Threshold is not needed.
	Data	POINTER TO DINT		11: Address of Data (ARRAY or VALUE with ADR on Data of FB) Input value as single value or as ARRAY for the possible values. As the input is a POINTER TO, it has to be connected to a preceding ADR-Operator, to which any available input-type can be provided: BOOL, BYTE, INT, UINT, DINT, UDINT, REAL or an ARRAY of these data types
Output	ErrorID	ERROR_ID	NO_ERROR	3: Shows error, Refer ERROR_ID enumeration for details of the error
	State	zLOG_ENUM_STATE	zLOG_IDLE	4: Actual state of LogInput, enumeration of Type zLOG_ENUM_STATE
	InExecution	BOOL	FALSE	5: A command was received when InExecution=TRUE - write datasets is carried out
	Overflow	BOOL	FALSE	6: Overflow, FIFOin is full, datasets are rejected. Output will be TRUE, if an overflow occurs. On this output a rising edge (FALSE -> TRUE) shows that communication/logging request occurred too fast and therefore the SRAM-FIFOin is full
	FifoInLevel	DINT	0	7: Level FIFOin (0…161)
	FifoInNextWrite	DINT	0	8: Next write position in FIFOin
	FifoInMaxLimit	DINT	0	9: Maximum limit of FIFOin - Standard value 161
	NumberItems	DINT	0	10: Number of Items since Enable=TRUE
	NumberOverflow	DINT	0	11: Number of Overflow items since Enable=TRUE
