TECHNICAL
NOTE
Solution Overview
Six MicroHAWK ID-40 readers are connected in daisy chain configuration to an Omron NJ/NX machine controller
via EtherNet/IP. The NJ/NX controller sends a trigger to the readers, and once a reader decodes a symbol, the
read cycle is stopped for all readers. This solution includes a basic HMI user interface and an NA series panel.
This solution is useful in food and commodity applications in which a decode must be performed on a product's
barcode, but the barcode's location on the product's perimeter is not known. One example is the need to
decode a GS1 Data Matrix on a product as it travels down a conveyor. After the decoded data has been
delivered to the NJ/NX controller, the data could be written to a database as part of a pharmaceutical company's
serialization and traceability implementation.
