MachineData - Machine data

Base

The \MachineData\Base\ subfolder contains the base classes of the machine data handling.

Classes

Name	Description
FB_MdBaseContainer	Represents the base container for machine data.
FB_MdBaseComponent	Represents the base class for machine components.

Components

The \MachineData\Components\ subfolder contains all the machine data components that have already been implemented. All included components inherit from the FB_MdBaseComponent class and have an enumeration that defines the index (without offset) of the individual parameters.

Classes

Name	Use	Description
FB_MdFileInfo	FB_MdBaseContainer	Contains the information of a saved file.
FB_MdActuator	FB_ActuatorFunctions	Contains actuator-specific parameters.
FB_MdAnalogValue	FB_Monitoring FB_Setpoints FB_Blowing	Contains scaling parameters for analog values.
FB_MdBlowpin	FB_Blowpin	Contains blowpin-specific parameters.
FB_MdClamp	FB_Clamp	Contains clamp-specific parameters.
FB_MdWtc	FB_Wtc	Contains Wtc-specific parameters.
FB_MdWtcTimer	FB_WtcTimer	Contains WtcTimer-specific parameters.
FB_MdAxis	FB_Axis	Contains general axis parameters.
FB_MdContinuousMotion	FB_Extruder	Contains parameters for axes with continuous rotary motion.
FB_MdHoming	FB_Homing	Contains setting parameters for homing procedures.
FB_MdNc	FB_NcFunctions	Contains NC-specific parameters.
FB_MdPtpMotion	FB_PtpMotion	Contains parameters for PTP-based motion.
FB_MdTrafo	FB_TrafoFunctions	Contains parameters for transforming axes.
FB_MdTempChannel	FB_TempChannel	Contains parameters for a temperature channel.
FB_MdTempGroup	FB_TemperatureGroup	Contains data of the temperature group.
FB_MdTempGrouping	FB_TemperatureGroup	Extends FB_MdTempChannel with a read mode for reading the configuration files.
FB_MdTempSupply	FB_TempSupply	Contains parameters for a temperature supply unit.
FB_MdTempTimer	FB_TempTimer	Contains additional information for the TimeSchedule of a temperature zone.
FB_MdTempZone	FB_TempZone	Contains parameters of a TF8540 temperature zone. Is the basis for FB_MdTempChannel.
FB_MdWeekdayTiming	FB_TimerWeekdayHmi	Contains data about the TimeSchedule of the Weekday Timer.

	Create your own machine data components The standard of TF8560 machine data applies for creating your own machine data components. A new component must implement the abstract methods `MdNextParameter()` and `MdSetParameter()` and set some internal variables. For this it is recommended to use the existing classes as a template and to follow the instructions of the TF8560 documentation.

Hmi

In the \MachineData\Hmi\ subfolder, classes are defined that summarize the data stored per component for the HMI.

	FB_MdHandleHmi This class is used to provide the information in the machine data file and an interface for the HMI. Accordingly, load and save commands for the machine data can be triggered directly from the HMI. Provided classes of Plastic Base Application, which offer both machine data and a HMI class, offer the class as an instance `fbParamHandle`.

	Access to the Md-HMI function blocks is not recommended The Md-HMI function blocks are only to be used for the automated creation of parameter pages in the HMI. As these function blocks only provide reference access to other objects, it is recommended to use the parameters directly at the source locations. The source location can be determined using the `MdXyzParameter()` methods of the associated MD function block. Alternatively, the source locations can be viewed via the FB_MdXyz descriptions. Example of correct source access: Instead of `FB_MdAxisHmi.DriveReversed`, use the axis interface `I_AxisBase.MotionParams.DriveReversed` directly.

Subitems

The \MachineData\Subitems\ subfolder contains several classes, interfaces and enumerations that contribute to the functionality of the machine data classes.
