6. Function blocks
6.3 UF - User function block
Figure 206: UF Blinker1 user function block used in the main program
The function block will be shown with its name, version, and configured inputs/outputs.
The function block type will be "UF", followed by the instance number (01 to 127).
Once you have dragged it, the user function block will be shown with a brown icon,
which means that is being used in the project.
Inputs/outputs wiring
The digital and analog inputs and outputs can be connected the same way as for any
other function block. In the example below, the user function block's Q1 output is con-
nected to a counter relay's C input.
