OPC Data Acquisition

Genesis OPC Explorer 3.1

• OPC Data Id: the Identifier (Id) of the record in the Genesis OPC Explorer 3.1 database.
• OPC Data Acquisition Time: the Date and Time of actual OPC Data Acquisition
  The format is always the same: YYYY/MM/DD HH:MM:SS.mmm
• Acquisition Rate: the actual acquisition rate, that is the time between current and last acquisition
  In normal circumstances, this figure should be equal or near to the minimal acquisition rate
• Total Acq. Gap: the gap between the calculated time and the actual time for OPC Data acquisition
  Calculated Time is obtained by multiplying the record number by the acquisition time from the OPC Data Acquisition Start
• Tags Value: the OPC values (according to the Project Setup)
