8 Analog Function Block

You can use Analog Function Blocks to perform a variety of statistical operations on the values of the

data points in your network, and store the result of each operation in an output data point. You can

perform these operations on as many input data points as you like per Analog Function Block. The

operations you can perform on them include determining the average value of the input data points, the

maximum value of the input data points, the minimum value of the input data points, the sum of the

input data point values, and several others. Each operation is described in detail later in this chapter.

You can also select a comparison function as your operation. In this case, the Analog Function Block

will compare the value of all the input data points to the value of a data point selected as the compare

data point. You can choose from a variety of comparisons that an Analog Function Block can perform

between the data points, including Greater Than, Less Than, and Equal To. The Analog Function

Block will compare the values of the compare and input data point using that comparison, and update

the output data point to a True or False value based on the result of that comparison.

If you are using a comparison function, and your Analog Function Block has multiple input data

points, you can specify a percentage. If that percentage of the comparisons between the input and

compare data points returns True, the output data point will be set to True. Otherwise, it will be set to

False.

For example, consider a case where an Analog Function Block has five input data points and is using

Greater Than as the comparison function. Assume that the percentage is set to 50%. If the value of

50% (at least three) of the input data points is greater than the value of the compare data point, the

output data point will be set to True. Otherwise, it will be set to False.

The Analog Function Block will perform the operation you have selected for it each time any of its

input data points are updated, or at a timed interval you specify. You could use these calculated values

as a part of a control system or to monitor alarm conditions based on multiple inputs.

Overview of the AnalogFB XML File

The #8000010128000000[4].UFPTanalogFunctionBlock.xml file stores the configuration of the

Analog Function Blocks that you have added to the SmartServer.

You can create new Analog Functional Blocks using the Set function, or by manually editing the

#8000010128000000[4].UFPTanalogFunctionBlock.xml, and rebooting the SmartServer. You can

create up to 20 Analog Functional Blocks per SmartServer. You can add more than 20 Analog

Functional Blocks if you load the dynamic v40 XIF on your SmartServer and you operate your

SmartServer in Standalone mode. Note that using the v40 XIF with the SmartServer operating in LNS

mode (LNS Auto or LNS Manual) is not supported.

The following represents a sample #8000010128000000[4].UFPT

#8000010128000000[4].UFPTanalogFunctionBlock.xml file with one Analog Functional Block. This

Analog Function Block determines the maximum value of the value field of the nviClaValue_1 and

nviClaValue_2 data points on the Digital Output 1 and Digital Output 2 functional blocks on the

SmartServer, and stores that value in the value field of the nvoClsValue_1 data point on the Digital

Input 1 functional block on the SmartServer.
