FB_ProductionCounter

Implements a general counter for production-dependent data such as a piece counter or a production time counter.

Syntax:

FUNCTION_BLOCK FB_ProductionCounter EXTENDS FB_BaseMd

Name	Type	Access	Initial value	Description
Name	STRING	Get, Set	<SourceName>	Specifies the name of the class instance.
FB_ProductionCounter
SavingInterval	LREAL	Get, Set	10.0 [min]	Interval for saving the counter value in a machine data file.
SinceLastReset	I_ProductionDataComponent	Get	-	Counter value since the last execution of the Reset() method.
SinceProducing	I_ProductionDataComponent	Get	-	Counter value since the start of the current counting process.
SinceStart	I_ProductionDataComponent	Get	-	Counter value since machine start.
Total	I_ProductionDataComponent	Get	-	Counter value since the beginning of the machine production time.
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_ProductionCounter
NewPart(`bCLK`)	Logs a new part for the part counter.
Producing(`bIsProducing`)	Indicates that production is actively running.
FB_BaseMd
[`PROTECTED`] AddMdComp()	Adds a component of type I_MdComponent to the machine data container.
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.

Name	Description
Cyclic()	Cycle method - Call once per PLC cycle (default 10 ms)

Component	Description	Index range	Number of instances
FB_MdFileInfo	File information	0x0000 Fxxx	1
FB_ProductionCounterComponent	Counter `Total` and `SinceLastReset`	0x0010 8xxx	2

Type	Description
I_Base	Standard interface on FB_Base.
I_ProductionCounter	Standard interface on FB_ProductionCounter.
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
TwinCAT v3.1.4024.35	PC or CX (x64, x86)	Tc3_PlasticBaseApplication (>= v3.12.5.0)
