Note You can use a function block in a Function Block Application Editor window only
once. After the block has been dragged over, it will be grayed out on the menu and in the
configuration tree. To use one block’s output as inputs to multiple downstream blocks, wire
the output to both locations. To use one block’s output in multiple loops, refer to the
Defining Loops section.
The following figure shows how the Function Block Application Editor
looks with function blocks dragged onto it.
Connecting Blocks
To send data from one block to another, you must connect the outputs and
inputs. You can wire blocks manually or use a template. The help window
on the right side of the screen describes the input and output parameters and
how they can be connected.
All the necessary arrangements for broadcasting data over the bus are
automatically generated when you wire the function blocks together.
When you later download your project to the bus, this scheduling and
linkage information will be downloaded to all the link masters on the link.
Wiring Blocks Manually
To wire blocks manually, complete the following steps:
1. Click the Wiring tool on the Function Block Application Editor
toolbar.
2. Click one terminal you want to connect.
