Application Examples
Application Examples
The following examples demonstrate how the components described in previous pages
can be deployed in industrial applications.
Daisy Chain
Daisy chain configurations are used in applications such as product packaging, where
single items have multiple symbols. For example, a box with one symbol on the top and
symbols on either side requires at least three scanners to ensure that all symbols will be
decoded.
The highlighted areas below demonstrate how a daisy chain can be arranged. One scanner
is placed above the conveyor line and one scanner is placed on each side of the line. The
three scanners essentially function as a single scanner, and data is sent from the primary
scanner to the host or PLC.
