UPLOADHISTORY

I2

This item is used to perform an upload of the log period, event, daily and alarm in the device. Set this item to –1 to upload any records that have been logged since the last upload. Set this item to a positive number to upload a number of days' worth of records. The item value will be reset to zero upon completion of a successful upload, or to three if the upload failed.

AUTOHISTORY

I2

This item is used to perform an auto upload of the log period, event, daily and alarm in the device. The item value will be reset to zero upon completion of a successful upload, or to three if the upload failed.

AUTO_SYNCTIME

I4

This item is used to synch the time in the RTU. Set this item to 1 will trigger the synch or the action will be taken on every interval. The item value will be reset to zero, after a successful upload.

AUTOTREND

I2

AutoTrend/TrendNumberis used to retrieve trend data from the device. "/TrendNumber" is 0 based where 0 is the first trend, 1 is the second trend and so on. Trend output is data file only, no Electronic Flow Measurement (EFM) output. The value will return to zero if successful, and three if failed.

AUTOTRENDNAME

I2

AutoTrend/TrendNameis used to retrieve trend data from the device."/TrendName" is case sensitive and should match the trend name set up in the device. Trend output is data file only, no EFM output. The value will return to zero if successful, and three if failed.
