The possible value types:
| Value type | The entry of start value and its interpretation | ||||||
|---|---|---|---|---|---|---|---|
| Logical | T* - True (word beginning with the character 'T'), otherwise False. | ||||||
| Integer | Integer number | ||||||
| Real | Real number | ||||||
| Absolute time | Time in the form of HH:MI:SS DD-MM-YYYY. | ||||||
| Relative time | Time in the form DDD HH:MI:SS.MSS. | ||||||
| Text | Text | ||||||
| Name of an existing object in the system. | ||||||
| Another object of Device type (it is necessary to specify the Device definition for it) | ||||||
| The name of an existing object in the system that is part of the Device. |
The types from Logic up to Text are common value types and determine the value type of the corresponding column for objects of Structured variable and Database types. The Object type represents either a reference to an object, a structured variable item, a device item, or a value array item. Basically, it is a reference to another object of the D2000 system. Item of a structure, which includes the reference to an object, essentially copies a value of the given object. The Device and Internal Item types represent references to another D2000 object that is understood as part of the device. A naming convention is applied to it, and such an object can only be connected to one Device type object (unlike the Object type, where an object can be connected to multiple Devices and its name does not change).
