Logical connection
A connection from a source (output side) signal to a destination (input side) signal is called a “
logical
connection
.” If a logical connection is present in a configuration, the actual hardware signal will be
connected. A single wire can make a single logical connection.
Logical connections are possible only in the Configuration window and the User Module window.
Wires in the Area window or Zone window can be drawn for display only. Even in the Configuration
window and User Module window, you can also draw wires for display only.
■
Situations Where No Logical Connection Is Created
• Both sides are source (output side) signals
• Both sides are destination (input side) signals
• Two source (output side) signals are connected to a destination
• There are two destination (input side) signals, and the wire is not connected to a source (output
side) signal.
