Name	Description
AddNextComponent()	Adds the subsequent component to the component (list).
FB_EnergyCalc
Enable(`bExecute`)	Switches the recording on.
Init(`iTimeRef`)	Initializes the class with the reference to a system time.
Latch(`bCmd`)	Starts a new measurement start time.
FB_MdBaseComponent
[`PROTECTED`] ConfigCompType(`eCompType`)	Used with inheriting classes to initialize the encoding offset after `E_StandardCompType`.
[`PROTECTED`] ConfigCompTypeEx(`…`)	Used with the inheriting class to initialize the encoding offset.
[`PROTECTED`] NextString(…)	Simplified method for reading a text-based machine data parameter. This method is used within the MdNextParameter(...) Callback method.
