Event ª1cº ChannelAPI events (Continued)

Possible Cause and Resolution

20ªBackplane communications with PLC fault; lost requestº

Internal error: An attempt to write to the user-specified reference address to be used to hold the Detailed Channel Status Words failed internally.

21ªLANsystem-softwarefault;resumingº

The Service Request Processor component of PLC CPU rejected a request. Entry 3 contains the major-minor error code of the request. Entry 4 contains a unique request identification number.

22ªLANsystem-softwarefault;resumingº

Internal error: An attempt to find the channel machine corresponding to a given channel number has failed. Entry 3 contains the particular channel number.

23ªLANsystem-softwarefault;resumingº

Internal error: An attempt to synchronize Channel API operating parameters with those configured by the user failed.

24ªBackplane communications with PLC fault; lost requestº

Internal error: An attempt to register with the Backplane (PLC) Driver failed. Entry 3 contains an error status code describing the failure. Many error codes are defined, the most noteworthy is ffff. This indicates that the Backplane (PLC) Driver is not initialized. Consult GE Fanuc for the meaning of any other codes.

25ªLAN IF can't init-check parms; running soft Sw Utlº

Internal error: An attempt to allocate a queue header failed. This event causes the Ethernet Interface to restart. If this error occurs within the first 60 seconds after the Ethernet Interface was restarted or power cycled, the automatic restart will force the Ethernet Interface into the Soft Switch Entry utility.

26ªLAN IF can't init-check parms; running soft Sw Utlº

Internal error: An attempt to allocate a buffer pool failed. This event causes the Ethernet Interface to restart. If this error occurs within the first 60 seconds after the Ethernet Interface was restarted or power cycled, the automatic restart will force the Ethernet Interface into the Soft Switch Entry utility.

27ªLANsystem-softwarefault:abortedassoc.&resumingº

Internal error: A Channel Machine was issued an event when in an invalid state. Entry 3 identifies the aborted channel number. Entry 4 identifies the state. Entry 5 identifies the event. Valid state and event codes are defined in the description for Entry 2 = 5.

28ªBackplane communications with PLC fault; lost requestº

Internal error: An internal attempt to send a request to the Backplane (PLC) Driver failed. Entry 3 contains an error status code describing the failure. Valid codes are described in the description for Entry 2 = 24H. The backplane transfer class code associated with the transfer is contained in Entry 4. Valid class codes are defined in the description for Entry 2=19H

29ªLANdatamemory exhausted-checkparms;resumingº

Internal error: An attempt to allocate a new backplane transfer tracking structure failed. The backplane transfer class code to be used with the transfer is contained in Entry 3. Valid class codes are defined in the description for Entry 2=19H.

2a ªBackplane communications with PLC fault; lost requestº

Internal error: An attempt to allocate a status update structurefailed.

2b ªLANsystem-softwarefault;resumingº

Internal error: A NULL COMMREQ data block pointer was detected.
