ENIU sets outputs to their default states If control bits 1 and 2 are both 0 outputs are set to 0 When the Ethernet NIU has both primary and secondary controllers output bits 1 and 2 should be set the same by both If they are not the same the Ethernet NIU will use the values it received from the last controller that provided outputs before communications were lost Specifying Individual Output Defaults If the control outputs are set to have the outputs default instead of hold last state ordinarily all outputs will default to zero If that is suitable for the application no further action is needed However for some applications taking outputs to a safe state requires setting them to one or forcing analog outputs to individually specified values An optional procedure can be used to set up defaults for the Ethernet NIU Use of this procedure is described in appendix A 3 8 Series 90 30 Programmable Controller Ethernet NIU User s Manual January 2004 GFK 2296 Checking for Faults and Clearing Faults The regular exchange of status and control data provides the controller with the ability to check for fault conditions and clear faults Checking for Faults The application program in the controller s should monitor Ethernet NIU status bit 7 to check for faults Bit 7 Faults Exist 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Word 1 Status and Fault Data O 1 2
