FB_AdaptableSequence

Allows variable extension of implemented procedures of a class. The class itself is used to manage all sequences and to indicate the state of a single sequence with reference to the management (master).

Syntax:

FUNCTION_BLOCK FB_AdaptableSequence

Properties

Name	Type	Access	Initial value	Description
ActiveSeq	I_AdaptableSeqItf	Get	THIS^	Interface to the current step of the procedure.
Done	BOOL	Get, Set	FALSE	Indicates successful processing of a procedure step.
Failed	BOOL	Get, Set	FALSE	Indicates the failed execution of a procedure step.
Index	BOOL	Get	0	Index of the class in relation to the overall procedure.
IsActive	BOOL	Get	FALSE	The class is active as the current sequence.
IsMaster	BOOL	Get	TRUE	The class is the management object of a procedure.
Length	INT	Get	0	Length of the list of appended procedure steps.
Next	I_AdaptableSeqItf	Get	NULL	Interface to the next step of the procedure.
Tag	I_FlexValue	Get	<Local>	Arbitrary value for saving user-defined information.

Methods

Name	Description
Append(`iNew`)	Appends a step to the procedure.
Check()	Checks whether the current step of the procedure has been processed.
Clear()	Deletes all sequences from the master.
Exists()	Checks whether a sequence is included in the master.
Idx()	Returns the xth step from the procedure.
Insert()	Inserts a step in the procedure.
Jump()	Requests jumping to a sequence that does not follow.
Reset()	Slave: Resets the state of the procedure step. Master: Resets the progress of the entire procedure.
[`INTERN`] SetMaster(`ipMaster`)	Assigns a master to the procedure step. Notice Used by the Insert() method and does not need to be called separately.

Interfaces

Type	Description
I_AdaptableSeqItf	Interface for implementation as slave.
I_AdaptableSeqState	Interface for reading the sequence state.
I_AdaptableSeqQuery	Advanced interface for editing by the master.
I_AdaptableSeqMaster	Interface for implementation as master.
