AH500 Programming Manual 7. The download log in the PLC SR227~SR308 SR227: The maximum number of download logs which are stored in SR227 is 20. Every download log occupies 4 registers. The download actions which are recorded are numbered, as shown in the following table. SR228: The download log pointer points to the latest download log. When a download action is executed, the value of the download log pointer increases by one. The range of pointer values is 0~19. For example, the download log pointer points to the fourth download log when the value in SR228 is 3. The time when the downloading actions occur and the action numbers are recorded in SR229~SR30.
The corresponding functions of these data registers are as follows.
