If the power-up or reset is successful, the overload relay will enter into Run
Mode.
Run Mode
In Run Mode, the Ethernet/IP Communications Auxilliary will:
•
operate as a slave device to a master device on an EtherNet/IP network.
•
operate as a master device and scan up to six slave devices on a DeviceNet
network.
•
acccept messages from a master on the EtherNet/IP network.
•
send response messages, COS messages, or CYCLIC messages to a master.
•
support a Device Level Ring (DLR) for Caralog Number 193-
DNENCATR.
If a communication error is detected, the Ethernet/IP Communications
Auxilliary will either enter the Recoverable Error Mode or Unrecoverable Error
Mode.
Operating as a Slave Device to a Master Device
As stated, the Ethernet/IP Communications Auxilliary will operate as a slave
device to a master device on an EtherNet/IP network in Run Mode. The
EtherNet/IP NS LED will flash green if there are no network connections
established with an Ethernet/IP network master. When one or more connections
are in the “established’ state, the Ethernet/IP NS LED will illuminate a solid
green. When one or more connections are in the “timed out” state, the EtherNet/
IP NS will flash red.
Operating as a Master Device
As also stated, the Ethernet/IP Communications Auxilliary will also operate as a
master device and scan up to six slave devices on a DeviceNet network in Run
Mode. The DeviceNet NS LED will flash green if there are no connections
established with a DeviceNet slave device. When oneo or more connections are in
the “established” state, the DeviceNet NS LED will illumiate a solid green. When
one or more connections are in the “timed our” state, the DeviceNet NS LED will
flash red. If no slave devices are defined in the DeviceNet scan list, the MS LED
will flash red.
