Specifies the characteristic values of a channel which combines the values from other channels (ChannelsToProcess).

Object.AddCharacteristics(Minimum, Maximum, Monotony, NoValueKey)

Object

ProcessedChannel
Object with this method

Minimum

Double
Specifies the smallest value of the channel.

Maximum

Double
Specifies the greatest value of the channel.

Monotony

Specifies whether the channel values are monotone increasing or decreasing.
Enumeration with the following selection terms:

1	eMonotonyUnknown	Not calculated
2	eMonotonyIncreasing	Increasing
3	eMonotonyDecreasing	Decreasing
4	eMonotonyNo	Not monotone

NoValueKey

Specifies whether a channel contains NoValues.
Enumeration with the following selection terms:

1	eNoValueKeyNotCalculated	Not calculated
2	eNoValueKeyYes	Yes
3	eNoValueKeyNo	No

The following example generates the channel MyChannel in the Measurements channel group. The channel contains the values, which are added rowwise, of the 64-bit Real type DirectAccess channels from the Measurements channel group. The example then sets the characteristic values of the channel MyChannel.

    Call ProcessedChn.Channels.Add(Channel)
