Synopsis

Parameters
| Parameter | Meaning |
|---|---|
| t | Source time |
| dp1, dp2, ... | Original attributes |
| val1, val2, ... | Values to be assigned |
Return value
The function dpSetTimed() usually returns 0, in the event of a failure, however, it returns -1.
Errors
Errors can be retrieved with getLastError(). The return value is then the appropriate error code. An alert is issued in the event of non-existent data points, incorrect parameter transfers or spelling errors.
Description
The function dpSetTimed() assigns the values val1, val2, ... and the source time to the original attributes dp1, dp2, ..., which may be changed by the user (the user is allowed to change the original attributes "_value", "_active", "_exp_default", "_exp_inv" und "_per_active" as wel as the user defined bits "_userbit1", "_userbit2" bis "_userbit8". Original attributes are the attributes of the config "_original"), or the attribute "_corr.._value. Any number of pairs of modifiable original attributes and values can be transferred to the function dpSetTimedWait(). The data point attributes are transferred as a string, the data type of the value depends on the attribute in question.
In one dpSetWait() function it is not allowed to assign a value to the same data point attribute several times. In this event only the first assignment is accepted and the other ones are discarded. The return value is 0, an appropriate error can be retrieved with getLastError().
The time t may not predate 1.1.1970 0:0 (UTC).
If there exists no definition for a config or attribute, the following defaults are used and added internal:
| Function | Default |
|---|---|
| dpSet*() | _original.._value |
| dpGet() | _online.._value |
| dpGetAsynch() | _offline.._value |
| dpGetPeriod() | _offline.._value |
| dpConnect() | _online.._value |
| dpDisconnect() | _online.._value |
The history of alert configs whose time is set to 0, is not saved. The last value is, however, saved in the database.
