1. The MODULE STATUS LED should flash green for approximately 1/4
second, then red for 1/4 second. The MODULE STATUS LED will then
stay lit green and the NETWORK STATUS LED should flash green for
approximately 1/4 second, then red for 1/4 second before turning off. The
NETWORK STATUS LED and the MODULE STATUS LED will now
return to their standard indication.
2. The E1 Plus EtherNet/IP Module performs a duplicate IP address check to
verify another module is not assigned to the same IP address. If a duplicate
IP address is detected on the network, the NETWORK STATUS LED
turns solid red, the MODULE STATUS LED turns flashing red, and the
E1 Plus EtherNet/IP Module enters the Recoverable Error Mode.
If the power-up or reset is successful, the overload relay will enter Run Mode.
Run Mode
In Run Mode, the E1 Plus EtherNet/IP Module will operate as a slave device to a
master device. The NETWORK STATUS LED will blink green if there are no
network connections established with a network master. When one or more
connections are in the “established” state, the NETWORK STATUS LED will
turn solid green. When one or more connections are in the “timed-out” state, the
NETWORK STATUS LED will blink red. In the Run Mode, the E1 Plus
EtherNet/IP Module will:
• Accept messages from a master on the EtherNet/IP network.
• Send response messages, COS messages, or CYCLIC messages to a master.
If a communication error is detected, the E1 Plus EtherNet/IP Module will either
enter the Recoverable Error or Unrecoverable Error Mode.
Recoverable Error Mode
In Recoverable Error Mode, the E1 Plus EtherNet/IP Module’s MODULE
STATUS LED turns flashing red. The overload relays will respond to messages
that are specified in offline node recovery message protocol.
IMPORTANT
The E1 Plus EtherNet/IP Module protection functions are still
operational even without an established network connection.
