Device Loop Templet Appendix A Runtime Templates230 3BUR002418-600 ALOG STATE CHANGES FieldThis field provides the means to enable or disable logging of state changes for thisdevice (that is, an audit trail of device state change messages in a historical archive).Valid entries are:YES log state changes for this device. Each time the device loop isscanned the old and new states are determined. If the old and newstates differ, an attempt is made to send a state change message tothe Alarm/Event package which sends the message to the Historynode. If memory cannot be allocated for the state change message,the History node will display, NOCOMMAND in place of themissing device states. This indicates to the operator that at least onestate change was not logged.NO do not log state changes for this deviceDMND PROCESSING MODE Field,# LOOPS TO PRESCAN Field, andLOOPS TO PROCESS FieldThe DMND PROCESSING MODE field, # LOOPS TO PRESCAN field, andLOOPS TO PROCESS fields allow you to specify up to 5 loops to process alongwith this loop. The DMND PROCESSING MODE field is used to specify whetherthe loops are processed when this loop is normally processed or when it is demandscanned, or both. The # LOOPS TO PRESCAN field determines how many of thelisted loops are scanned before this loop and how many are scanned after. TheLOOPS TO PROCESS fields list the loops for this type of processing.Valid entries for the DMND PROCESSING MODE field are:NONE no extra processingNORMAL process loops as specified in the LOOPS TO PROCESS fields whenthis loop is normally scannedDEMAND process loops as specified in the LOOPS TO PROCESS fields whenthis loop is demand scannedBOTH process loops as specified in the LOOPS TO PROCESS fields whenthis loop is demand or normally scanned
