System Error: 0a
“Unsupported feature in configuration”
The PLC CPU firmware does not meet the minimum version level required
by the Ethernet communications software. CAUTION:
Logicmaster-TCP/IP or HCT applications may not work properly. Entry 3
indicates the lowest required CPU microcode version. Entry 4 indicates
the actual installed CPU microcode version.

System Error: 0b
(Not reported to CPU Fault Table)
This error indicates that TCP/IP parameter values (part of the soft switch
configuration in TCP/IP configuration mode for the Ethernet Interface)
were not received from the PLC CPU. Verify that the Ethernet Interface is
configured in the PLC CPU.

System Error: 0c
“LAN system - software fault; resuming”
The Ethernet Interface was unable to obtain the minimum required
privilege from the PLC CPU. Ensure that the PLC CPU protection setting

(e.g., passwords) are set so as to allow access. Entry 3 contains the
privilege from the PLC CPU. Ensure that the PLC CPU protection settings
(e.g., passwords) are set so as to allow access. Entry 3 contains the

“LAN system - software fault; resuming”
The IP address of the Ethernet Interface was not configured with a
“LAN system - software fault; resuming”
The IP address of the Ethernet Interface was not configured with a
non-zero value. Use the PLC Programmer (or GSM configuration editor)
to configure the Ethernet Interface with an IP address other than 0.0.0.0.
The Ethernet Interface is automatically restarted into the Soft Switch Entry

“LAN data memory exhausted - check parms; resuming”
This error occurs when a request is made for memory and no memory of
the requested size or larger is available. The size of the request is stored in
Entry 3 of the log event. This error can be caused by:
- Misconfigured memory pool sizes or percentages.

error and should be reported to GE Fanuc - NA. The Ethernet Interface is
automatically restarted. If this error occurs within the first 60 seconds afte
