Creating User-defined Blocks
Virtual function block for input interface
176
An input interface (I/F) block and output interface block will also be inserted
automatically. These two blocks are virtual blocks that will serve to assign
external I/O for the user-defined block.
4. Adjust the layout of the function blocks and insert an Advanced PID (Block
Model 012) and a Lead/Delay (Block Model 147) block. (Right-click and se-
lect them from the Register – Control Block on the menu.)
5. Set the I/O interfaces.
Setting the Input Interface
Connect the analog inputs to be input to the user-defined function block to
the input interface block. In this example, the PV input for the Advanced PID
(Block Model 012) block is connected to the right of the input interface block.
