FB_ALY_BandwidthClassificator_1Ch 1: Outputs

Name

Type

Description

ipResultMessage

I_TcMessage

Contains more detailed information on the current return value. This special interface pointer is internally secured so that it is always valid/assigned.

bError

BOOL

This output is TRUE if an error occurs.

bNewResult

BOOL

When a new result has been calculated, the output is TRUE.

bConfigured

BOOL

Displays TRUE when the function block is successfully configured.

eClass

E_ALY_Classification_Bounds

Class to which the input values belong (WithinBounds/Smaller/Bigger).

fbTimeLastEvent

FB_ALY_DateTime

Timestamp of the last change of the classification result.
