FB_MdAxis

FB_MdAxis 1:

This machine data component contains the additional parameters of a base axis.

FB_MdAxis 2:

Axis data is saved via TF8560

Since TF8560 version v12.12.0, the saving of axis parameters is supported directly by the TF8560 library. The parameters previously saved by this component can be found in the corresponding successor implementation.

Description

AddNextComponent()

Adds the subsequent component to the component (list).

FB_MdAxis

Connect(ipAxis, ipAxisHmi)

Connects the component with the necessary dependencies.

FB_MdBaseComponent

[PROTECTED] ConfigCompType(eCompType)

Used with inheriting classes to initialize the encoding offset to 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.

[PROTECTED] SetString(…)

Simplified method for writing a text-based machine data parameter. This method is used within the MdSetParameter(...) Callback method.
