Cm598CanopenSysDiag (FB)

FUNCTION_BLOCK PUBLIC FINAL Cm598CanopenSysDiag EXTENDS AbbETrig3

Get present system diagnosis

This function block provides diagnosis information which and how many nodes are configured and which and how many nodes are in active data exchange mode. Type of requested information can be selected via NodeStateType. Information about nodes signaling active diagnosis is not supported for this function block. Please use standard diagnosis functions instead, which are provided as device diagnosis. Since position in NodesState byte field corresponds to node id, NodesInState does not correspond to position in byte field but can be used as additional information. The function block behavior is implemented according to the ETrig Function Block

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Execute	BOOL	FALSE	A rising edge starts a single operation, the output Busy goes to TRUE. In the first cycle all other inputs are read and stored, afterwards they are ignored. A falling edge does not stop the operation. After Done = TRUE or Error = TRUE and Execute = FALSE all outputs will be reset. For executing another operation the Execute input needs to be retriggered by another rising edge!	AbbETrig3
Output	Done	BOOL	FALSE	Operation is completed without error (while outputs Busy and Error are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE	AbbETrig3
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbETrig3
	Error	BOOL	FALSE	Operation is stopped with error (while outputs Busy and Done are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE. The output ErrorID gives more details about the error.	AbbETrig3
Input	Device	IDeviceCM598Can		instance of CM598Can device
	NodeStateType	Cm598NodeStateType		node state type (configured or active)
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code describing error condition
	NodesInState	USINT	0	number of CANopen nodes in corresponding state
	NodesState	CM598CanopenNodeStates		node state array of booleans - to show system diagnosis
