Communicating with a PLCĆ5
Processor on a DeviceNet
Network
This application describes how to connect and configure an
AdaptaScan Bar Code Reader to communicate with a PLC-5
processor over a DeviceNet network in a master/slave mode. A 4
character Interleaved 2 of 5 bar code symbol is used in this
application.
The DeviceNet network has the following nodes:
•
AdaptaScan Bar Code Reader on node 3
•
1771-SDN DeviceNet Scanner on node 1
•
Computer running DeviceNet Manager Software on node 62
The DeviceNet terminal block in the reader’s wiring base connects
the AdaptaScan Reader to the DeviceNet network. The wiring base
has two DeviceNet terminal blocks; one for upstream connection and
one for downstream connection.
