7.8.2 Objects

An object is a software entity which can be used in equations. An object includes properties

and methods which can be invoked by equations. You have access to two objects:

Logger

and

Channel

7.8.2.1

Logger

The Logger object is a software representation of the physical logger. The properties

associated with a Logger are:

Table 1: Logger Properties

Name

Type

Description

LoggerName

String

name of the logger

LoggerType

Integer

type of the logger

Channel(i As Integer)

Object

channel object

SampleRate

Double

sampling rate of logging

NumberOfChannels

Integer

number of channels logger contains

RangeSize

Double

range size of logger, OWL logger specific

property

RangeResistor

Double

range resistor, OWL logger specific property

angeGain

The methods associated with a Logger are:

GetChannelIndexByNumber(ch_number As Integer) As Integer

This method gets the channel index of a given channel number. A channel index is the

sequential number of Logger object. A channel number is the number retrieved from the

physical logger.

GetChannelNumberByIndex(index As Integer) As Integer

This method gets the channel number of a given channel index.

GetChannelReading(index As Integer) As Double

This method gets the engineering value of the reading for the channel referenced by index.
