Section 11. Glossary 432 Format formats the selected CR800 memory device. All files, including data, on the device will be erased. LNCMD software A feature of LoggerNet Setup Screen. In the Setup Screen network map (Entire Network), click on a CR800 datalogger node. The File Retieval tab should be one of several tabs presented at the right of the screen. Fill and Stop Memory A memory configuration for data tables forcing a data table to stop accepting data when full. final storage The portion of CR800 SRAM Memory allocated for storing data tables with output arrays. Final Storage is a ring memory, with new data overwriting the oldest data. FLOAT Four‐byte floating‐point data type. Default CR800 data type for Public or Dim variables. Same format as IEEE4. IEEE4 is the name used when declaring data type for stored data table data. FP2 Two‐byte floating‐point data type. Default CR800 data type for stored data. While IEEE four‐byte floating point is used for variables and internal calculations, FP2 is adequate for most stored data. FP2 provides three or four significant digits of resolution, and requires half the memory as IEEE4. FTP File Transfer Protocol. A TCP/IP application protocol. full duplex Systems allow communications simultaneously in both directions. garbage The refuse of the data communication world. When data are sent or received incorrectly (there are numerous reasons why this happens), a string of invalid, meaningless characters (garbage) often results. Two common causes are: 1) a baud‐rate mismatch and 2) synchronous data being sent to an asynchronous device and vice versa.
