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).
For Controllers that support EtherNet/IP, the error code “n4” is displayed if an
error occurs in EtherNet/IP. In addition, the EtherNet/IP IP address can be dis-
played by pressing the IP address display switch.
• IP Address Display Example: When the IP Address is 192.200.200.2
The IP address is displayed from right to left after the display type.
• Display Type: EtherNet/IP IP Address
• Display Type: EtherNet/IP IP Address when BOOTP is Set
