16 ControlLogix DeviceNet Scanner Module
Publication 1756-IN566B-EN-P - April 2001
Interpreting 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 1 second
intervals.
What is Displayed?
As an example, the display for RUN toggles between the network
address and the mode:
A#01
RUN
If there is a problem, the display shows the network address,
followed by the MAC ID of the problem node, followed by the error
code. The display toggles through these elements until the error is
corrected.
A#01
N#33
E#72
The following table summarizes the codes.
Alphanumeric Status Codes
