Table 4.1 Function Block Application Toolbar Descriptions

Toolbar Item Name Description

FBAP Name This field shows the name of the function block application.

Loop Execution Time This field shows the default execution rate of the process loop.

Stale Limit This field shows the number of consecutive duplicate values that a function block

accepts before it labels the input data as stale (old data).

Errors Click this button to perform error checking, regenerate the schedule of the application,

and remove bad wires.

Pointer Click this button to drag and highlight objects on the screen.

Wiring Click this button to make connections between valid inputs and outputs. When you try

to make a connection, the NI-FBUS Configurator checks the data type of the input and

output you are trying to connect, and highlights the connection if it is valid.

Loop Click this button to isolate certain function blocks from the default execution time. The

default execution time on the toolbar is the execution rate for all blocks on the

Function Block Application Editor. However, you can define multiple loops that run at

rates other than the default execution time. The Loop tool helps you to assign a

special execution rate to a group of function blocks. For more information about

running loops at different rates, refer to the Defining Multiple Loops section of this

chapter.

Block Click this button to show the block menu.

Monitor FBAP Click this button to enable graphical monitoring of the process.

change text in fields.

Zoom Click this button to zoom in and out. To zoom in, drag a rectangle around the area you

want to enlarge. To zoom out, right-click on the background of the Function Block

Application Editor window.

Execution Order Click this button to choose the order of execution for blocks. The NI-FBUS Configurator

automatically decides the order of the blocks, but you can change the default order by

using the Execution Order tool to click on the blocks in the order you want them to

execute.

Fill Click this button to fill objects on the screen with a color.

Fill Color Click this button to select a color to be used with the Fill tool.
