FB_TempConfigQueryHmi

This class (FB) is used to iteratively query the temperature configurations of a temperature group.

Syntax:

FUNCTION_BLOCK FB_TempConfigQueryHmi EXTENDS FB_ListQueryHmi

Name	Type	Access	Initial value	Description
Invoke	BOOL	Get, Set	FALSE	Triggering the data request via the HMI
FB_TempConfigQueryHmi
Active	BOOL	Get, (Set)	FALSE	The configuration data set is currently being used by the group.
GroupName	STRING(128)	Get, (Set)	‘Group {Index}‘	Name of the group in the configuration data set.
Note	STRING(128)	Get, (Set)	‘‘	User-specific note to describe the configuration data set.
Zones	INT	Get, (Set)	0	Number of zones that are grouped in the configuration data set.
FB_ListQueryHmi
Current	DINT	Get	0	Counter of the current entry that was transmitted. Is incremented implicitly when `Next()` is called.
Done	BOOL	Get, (Set)	FALSE	The PLC has transferred the last entry, the query process is complete.
Results	DINT	Get, (Set)	0	Counter of the total number of results that have been loaded. Must run ahead of the `Current` counter.
Select	DINT	Get, Set	0	Selection of a value read in the previous pass. The previous `Current` counter can be requested here for identification purposes, for example. A 0 is to be treated as no selection.
Valid	BOOL	Get, (Set)	FALSE	The current data entry is fully loaded and ready for further processing by the HMI.

Type	Description
Next()	Gives the signal to process another data entry. The method resets the `Valid` flag and increments the `Current` counter.
FB_ListQueryHmi
Reset()	Resets all values (except for `Invoke`) to the initial value.

Type	Description
I_ListQueryHmi	Standard interface on FB_ListQueryHmi.
I_TempConfigQueryHmi	Standard interface on FB_TempConfigQueryHmi.
