Table 1 - 1756-ENBT, 1756-EN2F, 1756-EN2T, 1756-EN2TXT, 1756-EN2TRXT, 1756-EN2TSC,1756-EWEB Modules Status Indicators
Status Indicator Description Status State
Module Status Display Alphanumeric display that scrolls messages. For example,
when a module is operating normally, the display scrolls
the module’s IP address. N/A N/A
Link Status (LINK) Indicates the module’s current state with respect to
transmitting data on the EtherNet/IP network. Off One of these conditions exists:
• The module is not powered.
– Verify there is chassis power.
– Verify that the module is completely inserted
into the chassis and backplane.
– Make sure the module has been configured.
• No link exists on the port.
Flashing green Activity exists on the port.
Green Activity exists on the port.
OK Status (OK) Indicates the module’s current state. For example, this
status indicator indicates if the module is executing
power-up testing, in the process of a firmware update or
operating normally. Off The module is not powered.
• Verify there is chassis power.
• Verify that the module is completely inserted into
the chassis and backplane.
• Make sure the module has been configured.
Flashing green The module is not configured. The Module Status
display scrolls: BOOTP or
DHCP<Mac_address_of_module>
For example: BOOTP 00:0b:db:14:55:35
Configure the module.
Green The module is operating correctly. The module’s IP
address scrolls across the Module Status display.
Flashing red The module detected a recoverable minor fault. Check
the module configuration. If necessary, reconfigure
the module.
Red The module detected an unrecoverable major fault.
Cycle power to the module. If this does not clear the
fault, replace the module.
Network Status (NET) Indicates if CIP connections are established. Off One of these conditions exists:
• The module is not powered.
– Verify there is chassis power.
– Verify that the module is completely inserted
into the chassis and backplane.
– Make sure the module has been configured.
• The module is powered but does not have an IP
address. Assign an IP address to the module.
Flashing green The controller has an IP address and one of these
conditions exists:
• The module has not established any CIP
connections.
If connections are configured for this module,
check the connection originator for the connection
error code.
• One or more connections have timed out. For
example, an HMI or I/O connection has timed out.
Reestablish the connection.
