Configure the Scan List
Use RSNetWorx for DeviceNet software to configure the scan list for the
1756-DNB scanner module.
Refer to DeviceNet Modules in Logix5000 Control Systems,
publication
DNET-UM004 .
Monitor and Troubleshoot Devices in the Module Scan List
Use the alphanumeric display and the status indicators on the 1756-DNB
scanner module front panel to verify networked devices in the scan list are
operating correctly.
Interpret the Alphanumeric Display
Your 1756-DNB scanner module displays alphanumeric codes that provide
diagnostic information about your module. The alphanumeric display flashes
the codes at approximately one-second intervals.
As an example, the display for RUN toggles between the node address and
the mode of the 1756-DNB scanner module:
A#01
RUN
If there is a problem, the display shows the MAC ID of the problem node,
then the error code. The display toggles through these elements until the error
is corrected:
A#01
RUN
N#33
E#72
