FB_ManualFunctionHmi

The class is used to connect to a TF8550 ManualOperation control.

Syntax:

FUNCTION_BLOCK FB_ManualFunctionHmi EXTENDS FB_BaseHmi

Name	Type	Access	Initial value	Description
Name	STRING	Get, Set	<SourceName>	Specifies the name of the class instance.
FB_ManualFunctionHmi
Cmd	I_ManualFunctionCmdHmi	Get	-	Commands from the HMI.
DoSelect	BOOL	Get, Set	FALSE	Manual function should be selected for the central operating function.
IsSelectable	BOOL	Get, Set	FALSE	The central operating function can be selected to take over control.
IsSelected	BOOL	Get, Set	FALSE	The central operating function is connected and controls this manual function.
SelectCmd	T_ManualSelectCmd	Get, Set	0x0	Command of the central operating function.
SelectState	T_ManualSelectState	Get, Set	0x0	State of the central operating function.
SelectSupported	BOOL	Get, Set	FALSE	A central operating function is available for this manual function.
State	I_ManualFunctionStateHmi	Get	-	Feedback signals to the HMI.
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'.

	Central operating function The "Central operating function" provides for the use of an incremental encoder to operate the manual function. This is available, for example, in the class for the Beckhoff BlowMolding Panel PC (FB_CP22xx-1025). Use with another input device is also conceivable, but must be implemented in the project on a user-defined basis.

Name	Data type	Description
fbCmd	FB_ManualFunctionCmdHmi	Commands from the HMI.
fbState	FB_ManualFunctionStateHmi	Feedback signals to the HMI.

Name	Description
Reset()	Resets the error state of the class.
FB_BaseHmi
Init(`ipBase`)	Default initialization method to pass the base class.
FB_Base
SetHMI(`ipBase`)	General assignment method for an FB_BaseHmi extending class. Notice This method always fails in the FB_Base implementation. Overwriting is therefore absolutely necessary.
[`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.

Type	Description
I_Base	Standard interface on FB_Base.
I_ManualFunctionHmi	Standard interface on FB_ManualFunctionHmi.
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
TwinCAT >= v3.1.4024.54 (recommended) TwinCAT >= v3.1.4024.42 (required)	PC or CX (x64, x86)	Tc3_PlasticBaseApplication (>= v3.12.7.0)
