None
The E1 Plus EtherNet/IP Module is not receiving power
at the EtherNet/IP connector.
Check EtherNet/IP power and cable connections and the
power connection on the EtherNet/IP connector.
Green

Flashing (once)
Normal
The Network Status LED flashes green, red, and off once
during a normal power-up sequence.
Green
Flashing
E1 Plus EtherNet/IP Module is online but with no
connections established.
Check EtherNet/IP master and its scan list for correct
scanner configuration.
Green
Solid
Normal operating state, and the E1 Plus EtherNet/IP
Module is allocated to a master.
No action required.
Red
Flashing
One or more connections timed-out.
Reset EtherNet/IP master device.
Red
Solid
1. Diagnostics test failed on power-up/reset. Internal
fault exists.
2. Duplicate EtherNet/IP module address exists (two
EtherNet/IP modules cannot have the same address).
3. A fatal communication error occurred.
1. Cycle power to the unit and network. If the fault still
exists, replace unit.
2. Change the IP address to a valid setting and reset the
device.
3. Check EtherNet/IP media for proper installation.
ATTENTION: If the outputs are to be commanded via an explicit
message, ensure that there can never be an established I/O
connection that can actively control them, and that the explicit
message connection has a non-zero expected packet rate (EPR)
setting.
