Add a function block from an exchange file

Import function blocks previously exported as exchange files (*.txf). Importing exchange files enables reusing function blocks in different
Trusted®
projects.
TIP: Importing a program, function, or function block imports its logic, local variables, local defined words, and description. Program, function, and function block comments, Diary files, and Modbus® extended attributes are not imported.
When importing a program organization unit (POU), specify a unique name within the project.
