Diagnostics
Linking Device is Offline Use these diagnostic checks to help you identify and fix the problem when the
linking device goes offline.
Table 3 - Linking Device is Offline Diagnostic Checks
Symptom Checks
The I/O tree in the Studio 5000 Logix Designer application shows
an orange triangle next to the linking device, and the module
cannot be seen from the Add-On Profile (AOP).
Does the linking device have power, and did it powered up?
Verify that the LCD backlight is on and information is displayed on the LCD screen.
Can you ping the linking device?
Verify that the linking device is on the same local Ethernet network when a ping is sent, and the computer
network address is the same subnet.
Example:
• Linking device IP address: 172.30.187.120
• Linking device subnet mask: 255.255.255.0
• Computer IP address: 172.30.187.1…172.30.187.254
Does the linking device have an IP address?
Examine the linking device LCD and verify that there is an IP address,
or that BOOTP is active.
Verify that the IP address of the linking device is in the same subnet range as that of the Allen-Bradley Ethernet
module.
• Linking device IP address: 172.30.187.1…172.30.187.254
• Linking device subnet mask: 255.255.255.0
• Ethernet module IP address: 172.30.187.1…172.30.187.254
• Ethernet module subnet mask: 255.255.255.0
Verify that no duplicate IP address exists on network.
Examine the LCD on the linking device to see if it indicates an IP conflict.
Verify that the Ethernet cable is plugged into the linking device.
Verify that the Ethernet status indicators are on, or flashing.
Note: the status indicators flash when there is data exchange.
• Yellow status indicator = 10 Mbit/s
• Green status indicators = 100 Mbit/s
Verify that the Ethernet cable length from the linking device to the switch is less than 330 ft (100 m).
