Meaning
All values listed with “Atomic Read” are to be read as a single block. They use a data locking mechanism in the SD230 code to prevent update to
these values once a read is initiated and until it is completed for all parameters.
Reports are read by setting two tags: Prime_ReportEnableChn which selects the channel from which to read, and Prime_ReportIndex which
selects which of the eight reports stored in the SD230 is read. Prime_ReportIndex = 0 selects the most recent report while Prime_ReportIndex =
7 selects the seventh most recent. Acceptable values for Prime_ReportIndex are 0 through 7.
Report number is a modulo 32768 count of the reports sent by the LH200. This count originates in the LH200 and is used to detect
dropped/missing reports by the application program. When the LH200 online coil is zero, the report number shall be set to 65535 to indicate the
report parameters may be invalid.
