Add a user-defined function

Use the
User-Defined Functions
 node in
Project Organizer
 to create logic programs for controller projects.
User-defined functions (UDFs) define a simple calculation that requires only one output. Once a UDF is created, the UDF is added to the instruction block element and can be reused like other function blocks in
FactoryTalk Design Workbench
.
TIP: The UDF input parameters support the array and structured data types. The UDF output parameter only supports simple data types.
Create UDFs in the following programming languages:
  • Function block diagram (FBD)
  • Ladder diagram (LD)
  • Structured text (ST)

  1. In
    Project Organizer
