14 Predefined Events
If a program checks for the nv_update_succeeds event, it must check for the
nv_update_fails event as well. The alternative is to check only for
nv_update_completes. A program is also permitted to check only for
nv_update_fails as long as there is no use of nv_update_completes or
nv_update_succeeds for any network variable.
Syntax
nv_update_succeeds [( network-var )]
nv_update_succeeds [( network-var1 .. network-var2 )]
network-var A network variable identifier, a network variable array
identifier, or a network variable array element. A range
can be specified with two network variable identifiers or
network variable array elements separated with a range
operator (two consecutive dots). The range is defined by
the indices of the referenced network variables. If the
parameter is omitted, the event is TRUE when any
network variable update succeeds.
Example 1 – Event for a Single Network
Variable
network output SNVT_abs_humid nvoHumidity;
...
nvoHumidity = 32;
...
when (nv_update_succeeds(nvoHumidity))
{
...
}
Example 2 – Event for a Network Variable
Array
network output SNVT_abs_humid nvoHumidity[4];
...
nvoHumidity[1] = 32;
...
when (nv_update_succeeds(nvoHumidity))
{
...
}
Example 3 – Event for a Range of Network
Variables
network output SNVT_abs_humid nvoHumidity1, nvoHumidity2,
