Overview
Distributed (DeviceNet Master/Slave, DH-485)
The distributed application below shows three Readers scanning bar
codes at different points in an assembly process. Data from any
Reader is individually sent to a controller. The discrete I/O on each
Reader provide distributed control independent of the PLC
monitoring the process.
Controller
Reader
identifies major sub-assemblies for routing to the proper
final assembly area. Reader
verifies the product code on the
assembled product being shipped. Reader

shipping label matches the product code. PLC
