SI 67 |
SD Card, Read Files: Status |
Value 0= No error 1= No SD card in Slot 2= Vector is not long enough to contain data (may be at upper address limit of that data type) 3= Path to SD file not found 4=Another file is currently open 5 = File is closed 6 = Busy: previous request in progress 7 = File Open Error 8 = Read Error 9 = File Close error |
SI 67 reports status for the following SD File utilities:

SD Card, Write Files: Status |
Value 0 = No error 1 = No SD card in Slot 2 = Vector is not long enough to contain data (may be at upper address limit of that data type) 3 = Path to SD file not found 4 = Another file is currently open 5 = File is closed 6 = File Open error 7 = Write Error 14 = File Close error |
SI 68 reports status for the following SD File utilities:

SI 69 |
SD Card: File Open Time (may signal file fragmentation) |
Time required to open SD files, in units of 10mSec. |
Each time a file is opened, the OS updates this value. A typical first write (open + write) = approx. 500mSec, typical first read (open + read)= approx. 60mSec
Over time, this may increase due to file fragmentation.
If the time becomes to great, the card should be reformatted Reset at Power-up and when SD card is removed. |
SI 76 |
SI 76 Number of Alarms currently in History Buffer |
Shows the number of Alarms in the history buffer. |
If SB 352 SD: Write Alarm History to SD is ON, the Alarms in the buffer are automatically written to the SD card. Initialized by the user, or when the PLC is initialized. |
