FB_Temperature

Main class of temperature control to manage all temperature channels and groups.

Internal functions:

FUNCTION_BLOCK FB_Temperature EXTENDS FB_BaseMd

Name	Type	Access	Initial value	Description
Name	STRING	Get, Set	<SourceName>	Specifies the name of the class instance.
FB_Temperature
DisableAlarms	BOOL	Get, Set	FALSE	Suppresses alarms triggered by errors of a temperature channel.
DisableMessages	BOOL	Get, Set	FALSE	Suppresses debug messages of the TF8540 library.
EnableCallback	BOOL	Get, Set	TRUE	Enables communication with the I/O components.
EnableConfig	BOOL	Get, Set	TRUE	Enables the configuration of all temperature channels.
EnableLooptest	BOOL	Get, Set	FALSE	Enables current monitoring of all zones.
LibScopeVars	REFERENCE TO FB_Scope_TempCtrlVariables	Get	-	Access to an overview of TF8540 live data.
Timer	I_TempSchedule	Get	NULL	Access to the connected scheduler.
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_Temperature
Channels(`x`)	Returns an interface to the xth temperature channel of TF8540.
CreateDefaultParams()	Creates a default parameterization for all temperature channels.
EnableAll()	Enables all temperature channels on the PLC side.
Groups(`x`)	Returns an interface to the xth temperature group.
LinkGroup()	Assigns a linear arrangement of temperature channels to a group.
LinkSupply()	Assigns a group to a supply channel.
LinkZone()	Assigns a temperature channel to a group.
SetScheduler(`iScheduler`)	Assigns a schedule to the temperature control.
StandbyAll()	Sets all temperature channels to standby.
Supply(`x`)	Returns an interface to the xth supply unit.
SupplyLines(`x`)	Returns an interface to the xth supply channel.
UnlinkGroup(`x`)	Removes all temperature channels from the xth group.
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.

	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.

Name	Description
Cyclic()	Slow cycle method (default 25 ms)

ID	Description	Alarm/Message
20x	Invalid interface queried	Message

Component	Description	Index range	Number of instances
FB_MdFileInfo	File information	0x0000 Fxxx	1
FB_MdTempSupply	Parameters of the supply units	0x0000 4Dxx	4 (Default)
FB_MdTempGroup	Grouping configuration	0x0000 4Exx	5 (Default)

Type	Description
I_Base	Standard interface on FB_Base.
I_Temperature	Standard interface on FB_Temperature.
I_TempTaskInterface	Runtime interface for a slow PLC task.
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
