The Ethernet Unit will output error status to the following word in the CIO Area
of the CPU Unit. This information can be used in troubleshooting errors.
Word = CIO 1500 + (25 x unit number) +18
9 8 7 6 5 4 3
Address mismatch
EEPROM error
The corresponding bit will turn ON when an error occurs
Check the transceiver or transceiver cable.
The following cannot be used as IP address settings.
• Host IDs that are all 0 or all 1.
• Network IDs that are all 0 or all 1.
• Subnetwork IDs that are all 1.
• Addresses beginning with 127 (7F Hex).
Reset the IP address.
Correct the IP address table. If the problem persists, replace the CPU Unit.
Correct the IP router table. If the problem persists, replace the CPU Unit.
Correct the routing tables. If the problem persists, replace the CPU Unit.
Check the transceiver, transceiver cable, or cable.
Make sure that the node number and the last byte of the IP address are the same
and set other host IDs to 0.
Change the address conversion method.
Restart the PC. If the problem persists, replace the Ethernet Unit.
The Ethernet Unit provides an error log that records errors that have occurred
during Ethernet Unit operation. The contents of the error log can be read or
cleared from a Programming Device, such as the CX-Programmer, or it can
be read or cleared using FINS commands from a workstation or computer.
(See 11-3-7 ERROR LOG READ and 11-3-8 ERROR LOG CLEAR).
The following errors are recorded in the error log.
• Errors in network operation
• Errors in data transfers
• Error in the CPU Unit
