Seven-segment Display
The 7-segment display indicates the NE1A-series Controller’s node address
during normal conditions, and the error code and the node address of the
error during error conditions. Also, “nd” is displayed during normal conditions
if DeviceNet communications are disabled (i.e., Standalone Mode).
Note
The errors are indicated by the combination of the MS indicator, NS indicator,
and the 7-segment display. For further details on specific meanings, refer to
Section 10 Troubleshooting.
