Communicating with an SLC
5/03 Processor on a
DeviceNett Network
This application describes how to connect and configure an
AdaptaScan Bar Code Reader to communicate with an SLC 5/03
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
•
1747-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.
The hardware items required for this application are:
•
2755-SN3, -SN5 or -SN8 AdaptaScan Bar Code Reader
•
2755-NB40 or -NB41 Wiring Base
•
2755-PW46 or -PW47 Power Supply (if not power by DeviceNet)
•
2755-NC43 or -NC48 Configuration Cable
•
1747-SDN Scanner Module (v2.05 firmware or later)
•
1770-KFD DeviceNet RS-232 Interface Box
•
RS-232 cable for the RS-232 Interface Box
•
DeviceNet trunk cable
•
1746 Chassis and 24V dc Power Supply
•
SLC 5/03 processor
•
Computer running Windows 3.1 (or later) or Windows 95
•
9-to-25 Pin Adapter (for Computer with 25-pin COM port)
The software requirements for this application are:
•
2755-ASN AdaptaScan Offline Programming Software (v8.0 or later)
•
SLC Advanced Programming Software
•
1787-MGR DeviceNet Manager Software (v3.0 or later)
