FB_BlowpinHmi 4: Methods

Name

Description

Reset()

Resets the error state of the class.

FB_PtpMotionHmi

Moves(x)

Returns an interface to the x-th Move-Cluster.

FB_BaseHmi

Init(ipBase)

Default initialization method to pass the base class.

FB_Base

GetHMI()

Returns the assigned HMI object.

Notice The method is not implemented in the FB_Base class. If the method is not overwritten by inheritance, a pseudo variable is always returned.

SetHMI(ipBase)

General assignment method for an FB_BaseHmi extending class as a local HMI.

Notice The method is not implemented in the FB_Base class. If the method is not overridden by inheritance, it always fails.

[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.

FB_BlowpinHmi 5:

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.
