Class for the use of weekday timers in connection with temperature control.

Syntax:

FUNCTION_BLOCK FB_TempSchedule EXTENDS FB_TimerWeekdayMaster

Name	Type	Access	Initial value	Description
Name	STRING	Get, Set	<SourceName>	Specifies the name of the class instance.
FB_TimerWeekdayMaster
Elapsed	LREAL	Get	0.0	Current time value in seconds
Latched	LREAL	Get	0.0	Stored time value of the last execution in seconds
Preset	LREAL	Get, Set	0.0	Preset time value in seconds
Et	TIME	Get	T#0ms	Current time value in milliseconds
In	BOOL	Get, Set	FALSE	Activation input
L	TIME	Get	T#0ms	Stored time value of the last execution in milliseconds
Pt	TIME	Get, Set	T#0ms	Preset time value in milliseconds
Q	BOOL	Get	FALSE	Timer output
FB_BaseMd
MachineData	I_MdBaseContainer	Get	-	Interface for machine data handling.
FB_Base
BaseState	E_BaseState	Get	eNotHandled	Initialization state of the class instance.
Error	BOOL	Get	FALSE	Class is in an error state.
ResultMessage	I_AppMessage	Get	-	Access to the class-internal EventLogger.
[`PROTECTED`] _Name	STRING	Get	<SourceName>	`.Name` without leading 'fb'.

Name	Description
Reset()	Resets the error state of the class.
FB_TempSchedule
MemberSchedule(`x`)	Returns an interface to the first timer assigned to the group (member) x.
MemberScheduledActive(`x`)	Returns an interface to the first timer assigned to the group (member) x and currently active.
FB_BaseMd
[`PROTECTED`] AddMdComp()	Adds a component of type I_MdComponent to the machine data container.
FB_Base
GetHMI()	Returns the assigned HMI object. Notice The method is not implemented in the `FB_Base` class. If the method is not overwritten by inheritance, a pseudo variable is always returned.
SetHMI(`ipBase`)	General assignment method for an `FB_BaseHmi` extending class as a local HMI. Notice The method is not implemented in the `FB_Base` class. If the method is not overridden by inheritance, it always fails.
[`PROTECTED`] _QueryNamespace()	Extracts the first part of the instance path as an object namespace.
[`PROTECTED`] _QueryObjectName()	Extracts the last part of the instance path as the object name.

	Exceptions avoidance The list access functions (e.g. Channels(x), Groups(x), etc...) return a pseudo variable if the requested index is invalid. In addition, a message is thrown in the EventLogger.

Component	Description	Index range	Number of instances
FB_MdFileInfo	File information	0x0000 Fxxx	1
FB_MdTempTimer	Temperature attributes of a timer	0x0000 4Dxx	30 (Default)
FB_MdWeekdayTiming	Period of a weekly timer	0x0000 71xx	30 (Default)

Type	Description
I_Base	Standard interface on FB_Base.
I_TempSchedule	Standard interface on FB_TempSchedule
I_OneTaskInterface	Runtime interface for a PLC task
I_TimerWeekday	Standard interface on FB_TimerWeekdayMaster
I_BaseMd	Standard interface on FB_BaseMd.
I_BaseEmpty	For extension without standard interface.
I_BaseDev	Covers all methods and properties of the base class.

Development environment	Target platform	PLC libraries to include
