HINZ developed a machine vision system that automatically measures the amount and distribution of potash on a mining conveyor as it is loaded by the bridge conveyor. This information is used by the mine control system to automatically move the bridge conveyor to correct any imbalance.
Traditionally, body panels are inspected by using a robot to present the part to an array of proximity switches. Ford improved on this method by using machine vision. The camera connects to either the robot or the PLC using the Ethernet/IP protocol.
Unico Systems, a manufacturer of home air conditioning and heating systems, uses Cognex wireless handheld scanners to read barcodes on the product, and QR codes on employee badges and assembly stations. Operators now spend less time on data entry tasks and the production rate is up 40%

The need to use PCs to interface with vision systems and ID readers required the purchase of expensive hardware and development of sometimes complex software. A new generation of vision systems and ID readers with built-in EtherNet/IP connectivity streamlines factory network integration.
Exide had difficulties in reading 2D data matrix codes burned into plastic with a laser burner. The problem was solved by switching to image-based Cognex DataMan 200 readers with 2D decoding software and an EtherNet/IP interface to the PLC.
