SgxDiagnosis (FB)

FUNCTION_BLOCK SgxDiagnosis EXTENDS AbbLConC3

SgxDiagnosis function block performs diagnostics on “All classes”, “Sensor”, “Channel” or “Module”

DianosisType := 0 to diagnose all classes: “Sensor”, “Channel” and “Module”

DianosisType := 1 to diagnose sensor health (hardware, wiring or parameter)

DiagnosisType := 2 to diagnose channel health (hardware, wiring or parameter)

DiagnosisType := 3 to diagnose module health (hardware, wiring or parameter)

Diagnoistics start on “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
	DigitalOutput	BOOL	FALSE	Imaged digital output field when “general digital output” is configured
	DiagnosisType	Sgx_DIAGNOSIS_TYPE	0	0 => All; > 1 => Sensor; 2 => Channel; 3 => Module
	DiagnosisObject	Sgx_DIAGNOSIS_OBJECT	0	Diagnosis object: “hardware”, “wiring” or “parameters” of channel
	Channel	POINTER TO SgxChannelIo		Instance of strain gauge channel to be connected
Output	Active	BOOL	FALSE	0 => Diagnosis(ErrorCountReturn and ErrorCodeList) are in progress; 1 => ErrorCountReturn and ErrorCodeList are ready
	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	ERROR CODE
	StateReturn	WORD	0	State returned, [0] => digital output state;[1] => Done; [8:10] => calibration type, 1 = ZERO, 2 = TARE, 4 = TWO_POINTS_CALIBRATION; [11] => Eeprom; [12:15] = 2
	ErrorCountReturn	WORD	0	Error counts/numbers returned
	ErrorCodeList	ARRAY [0..3] OF BYTE	[4(0)]	Error code listed
