The FB and FC will be called inside OB1. Drag the FC from the project tree to a network. The function is now called inside OB1. To call a function block an instance databock needs to be made.

A function block (FB) is a code block that uses an instance data block for its parameters and static data. FBs have variable memory that is located in a data block (DB), or "instance" DB.

FBs and FCs receive parameters through the IN and IN/OUT interface types. The blocks process the parameters and return values to the caller through the IN/OUT and OUT interface types.

The FB interface also provides a "Default value" column that allows you to assign a new start value for the parameter as you are writing the program code. This default value in the FB is then transferred to
