Name

Type

Access

Initial value

Description

Connected

BOOL

Get

FALSE

Component is connected to its dependencies (except for the MD container).

FB_MdTempGroup

ConfigHash

T_SHA256

Get, Set

0

Hash value of the group configuration read or to be written.

ReadMode

BOOL

Get, Set

FALSE

The class does not transfer the data during the loading process, but saves it locally.

FB_MdTempGroup 4: Methods

Name

Description

AddNextComponent()

Adds the subsequent component to the component (list).

FB_MdTempGroup

ClearReadValuesRecurse()

Sets the data loaded in ReadMode to the initial value.
The method calls itself recursively for all subsequent elements in the linked container.

Connect(ipTempGroup, ipTempGroupHmi)

Connects the component with the necessary dependencies.

ReadModeRecurse(bReadMode)

Sets the ReadMode equal to the input variable.
The method calls itself recursively for all subsequent elements in the linked container.

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.

[PROTECTED] SetString(…)

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

Name

Description

MdNextParameter(…)

Container call for saving the parameters in a file, implemented by FB_MdComponent.

MdSetParameter(…)

Container call for loading the parameters into the runtime, implemented by FB_MdComponent.
