Clicking on this button inverts the filter. The button changes from = to <> and vice versa.

EFB

When you activate this check box, the instances of elementary function blocks (EFBs) are displayed.

DFB

When you activate this check box, the instances of derived function blocks (DFBs) are displayed.

Named by default

When you activate this check box, the function block instances are displayed whose default names (e.g. FBI_19_3, TON_1) have not been changed.

Name

This column displays the names of the function block instances and their formal parameters (inputs, outputs).

no.

This column displays the order number of the formal parameters in the function block.

Type

This column displays the types of the function block instances and the data types of their formal parameters (inputs, outputs).

Value

This column displays the initial value of the formal parameters.

Comment

This column displays comments about the function block instances and their formal parameters (inputs, outputs).

HMI Variable

This column displays if the formal parameter is embedded in the data dictionary.

R/W Rights of Referenced Variable

This column displays the access rights when the formal parameter is a Reference data type.
NOTE: Help for the Type.

Hold down the Alt+F1 keys and then click on the function block type for which you wish to access Help.
