12-1212.3.2 System ErrorThis error code notifies the user if a critical system error has occurred.If this error occurs, the E2 LED on the front panel of the ET-LAN unit lights.Code Name Description Step to take Remark9001H System errorduring normaloperationA watchdog error occurred (theALARM LED is lighted.)The unit has run away.Turn the power supply offand then on again.These are systemerrors that canoccur duringnormal operation. Ifone of these errorsoccurs, the E2 LEDon the front panelof the ET-LAN unitlights.9002H The unit transmission sectionsent notification of a memoryaccess error.Turn the power supply offand then on again.9003H There is no longer enoughbuffer space available in theapplication processing.9004H There is no longer enoughbuffer space available in theprotocol processing.9005H The EEPROM Ethernetaddress cannot be readsuccessfully.9006H The CPU unit has run away, ora version of the CPU unit isbeing used that is notsupported by the ET-LAN unit,so the CPU unit cannot berecognized.Problem with the CPU unitCheck the contents of.Check the CPU unitversion.9010H Test modeexecution resultsAn error was discovered duringthe ROM test.Turn the power supply offand then on again.These are errorsthat occur duringtest operation. Ifone of these errorsoccurs, the E2 LEDon the front panelof the ET-LAN unitlights.9011H An error was discovered duringthe RAM test.9012H An error was discovered duringthe shared memory test.9013H An error was discovered duringthe EEPROM checksum test.9014H An error was discovered duringthe internal loopback test.9015H An error was discovered duringthe external loopback test.Check the transmissionline connections.9016H An error was discovered duringthe timer test.Turn the power supply offand then on again.12.3.3 Warning ErrorThis error code does not indicate a system error, but alerts the user to a certain condition or status.If this error occurs, the E2 LED on the front panel of the ET-LAN unit flashes.Code Name Description Step to take RemarkB003H No receptionbuffer. Data hasbeen destroyedat theconnectiondestination.In transparent communication,data was sent to a connectionwith a transparentcommunication reception buffersize of 0, so the data wasdestroyed.To receive the data,specify a transparentcommunication receptionbuffer area for thepertinent connection (thissetting becomes effectivewhen initializationprocessing is carried out).If this error occurs,the E2 LED on thefront panel of theET-LAN unitflashes.
