Internal data types
Data types, used in D2000 system, are listed in the following table.
| Data type | Range |
|---|---|
| LongInteger | -2147483648 ≤ x ≤ 2147483647 |
| LongReal | 0, 2.3x10-308 ≤ |x| ≤ 1.7x10308 |
| Time | 1.1.1972 - 31.12.2099. Time data accuracy in D2000 system is more then 1 µs (microsecond). |
| Text | Text strings with floating length are limited to 10 000 characters. The texts are internally encoded in UTF-8. |
Range of database types:
-1.0x1038 ≤ x ≤ 1.0x1038
This range implies the following restrictions relating to:
- configuration database - maximum size of real numbers used as limits in the configuration of eval tags, I/O tags, historical values, etc.
- archive database - maximum size of real data that can be stored in historical value archive
