TypeVar (Variable Datatype)
The variable for which to return the data type code. If the TypeVar parameter passed in is not a simple variable (i.e., is an expression or a constant) then 0 is returned.
See the following list for the data type code returned for different variable or data types. Note that these data type codes are for the CR6 dataloggers that use big-
endian Endianness refers to byte order. With the little-endian format, bytes are ordered with the least significant byte (the "little end") first. With the big-endian format, bytes are ordered with the most significant byte ("big end") first. The CR300, GRANITE 9, and GRANITE 10 dataloggers use the little-endian format. The CR800, CR1000, CR3000, CR6, CR1000X, and GRANITE 6 use the big-endian format. Byte order when sending string variables as serial data is identical in big-endian and little-endian CSI dataloggers. Only numeric values sent as multiple bytes require attention to big-endian and little-endian issues. format. Dataloggers that use little-endian format (for example, CR300, CR350, GRANITE 9, GRANITE 10) return different data type codes.
| Code | Description |
|---|---|
| 1 | UINT1 – One-byte unsigned integer |
| 2 | UINT2 – Two-byte unsigned integer with most significant byte first |
| 3 | UINT4 – Four-byte unsigned integer with most significant byte first |
| 6 | Long - 32-bit integer with most significant byte first |
| 7 | FP2 - Two-byte floating point in final storage format |
| 9 | IEEE4 - Four-byte floating point in big-endian format |
| 11 | String - ASCII string |
| 14 | NSec – a composite of two Int4 values that represent a time stamp as seconds since midnight 1 January 1990 and nanoseconds into the second, respectively |
| 17 | Bool8- a bit field of 8 bits used for representing ports and flags |
