The Event Log occupies a block of 16000 Input registers in the Modbus table starting at address 40000 and proceeding through address 55999 It consists of a 5 register header at address 40000 followed by 1999 8 register event records starting at address 40008 As they are Input registers read with Modbus function code 4 no part of the Event Log can be written from outside the module but it is maintained exclusively by the AFC firmware As events occur they are recorded in the Log which acts as a circular file Each new event record overwrites the oldest one hence the log stores up to 1999 of the most recent events As each record is written the values in the header are updated to reflect the new status of the log Auditors may require the Log to be downloaded from time to time events are read from the module and stored in a more permanent database and the events So copied and archived are marked in the module as downloaded If all record positions contain events that have not yet been downloaded the log is full In this case the handling of a new event depends on the value of the Event log unlocked site option If the option is set then the log full condition is ignored and the new event overwrites the oldest one Since the overwritten event was never downloaded it is permanently lost If the option is clear then the Event Log is locked and the new event is rejected if possible and otherwise ignored Controllable ev
