Error Status Section 10-2
10-2 Error Status
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
The corresponding bit will turn ON when an error occurs
10-3 Error Log
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).

Bit Name Correction
01 Transceiver echo test error
(CS1W-ETN01 only)
Check the transceiver or transceiver cable.
02 IP address setting error 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.
03 IP address table error Correct the IP address table. If the problem persists, replace the CPU Unit.
04 IP router table error Correct the IP router table. If the problem persists, replace the CPU Unit.
06 Routing table error Correct the routing tables. If the problem persists, replace the CPU Unit.
07 CS1W-ETN01: Transceiver
error
CS1W-ETN11 and CJ1W-
ETN11: Cable error
Check the transceiver, transceiver cable, or cable.
14 Address mismatch 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.
15 EEPROM error Restart the PC. If the problem persists, replace the Ethernet Unit.
