FB_TimerHmi

HMI interface for IEC 61131-3 timer for setting process timings with a TF8550 TimerControl.

Syntax:

FUNCTION_BLOCK FB_TimerHmi EXTENDS FB_BaseHmi

Name	Type	Access	Initial value	Description
Name	STRING	Get, Set	<SourceName>	Specifies the name of the class instance.
FB_TimerHmi
ActualValue	LREAL	Get, Set	0.0	Current time value in seconds
LatchedValue	LREAL	Get, Set	0.0	Stored time value of the last execution in seconds
Out	BOOL	Get, Set	FALSE	Timer output (depending on TON, TOF, TP)
SetValue	LREAL	Get, Set	0.0	Preset time setpoint in seconds
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_BaseHmi
Init(`ipBase`)	Default initialization method to pass the base class.
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.

I_TimerHmi	Standard interface on FB_TimerHmi
I_BaseHmi	Standard interface on FB_BaseHmi.
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
