Write Blocks

Write Blocks are how you can write (override) a point's value. A write action must be triggered by another block.

Read Blocks

Read blocks are how you bring in point data into your FDD Routine or FTT Workflow.

Field

To assign a field to one of these blocks, click inside the "Field" input box and you will be presented with a dialog box where you can make a selection.  Points/fields available are scoped based on the entities you choose, so if you are not seeing a point you need, make sure that the entities selected contain that field.

Name

This is a free-form input where you can assign whatever name to this block you want. It is recommended, for easy reference, to set the name similar to the point name.

Primary or Supporting

For any FDD Routine, it can have only have one Read block designated as the primary reference point ("Master").  What this means, is when an event is generated for this routine, it  will use that point as the reference to other modules within KODE OS.  All other points that are not the Master, are Supporting ("Slave").

Read Arrays

What is a "Read Array"?

Within a device, it is possible to have two distinct fields/points that are of the same name.  In these cases, the field/point should be appended using an identifying number.  As a status of that field is an aggregate of these number-appended ones, FDD will identify their array potential and allow you to select that type.  

For example if you have two stages of compressor, determining if a compressor is running would look at both of these points and check if either of them was true. With arrays, instead of bringing both points into the routine to evaluate, you only have to bring in one read [array] block. This simplifies, not only the routine itself, but also the need to cover all variations of multiple stage compressors within a single routine.

Parameter Blocks

Parameters

Parameter blocks are a convenient way to customize parameters for projects used in workflows without having to edit the workflow itself. Values in parameter blocks are available when configuring a job using the workflow.

Input Fields

Name

When assigning this block its name, it's recommended to use a human readable name that can be understood by anybody. Doing this will help minimize confusion when accessed later to troubleshoot or understand the intent.

Hint

This field is a sting input that will appear when the information icon is hovered over when setting parameters. You are encouraged to use as many words as necessary to make sure the intent of the parameter is properly communicated.

Value

Aside from a few exceptions, every parameter assigned within a workflow will have a default value associated with it. When you edit the parameters when setting up a job, you are altering this input to the algorithm.

Arithmetical Blocks

Arithmetical

Use these blocks to perform mathematical operations on numbers set as inputs.

Array Operation Blocks

Array Operations

Although not always the most obvious choice, array operations can be very useful. Use these to perform operations across a series of data from the same source.

Examples of usage:

"Tell me the difference between the highest and lowest values over a 5 min period."

• Read Number -> Buffer Time (5min) -> Array Sort (Ascending) -> Array Delta

"Perform a 15 min rolled up average of this data"

• Read Number -> Buffer Time (15min) -> Array Mean
