думаю вот этот системный итем в DAS подойдет:
$SYS$UpdateInterval (DWord/ReadWrite)
Accesses the currently set update interval. It is the current update interval of the device group in milliseconds. A client can poke new values into this item.
The value of zero indicates that no non-system items on that topic are updated (data for these items are not acquired from the device).
RANGE:
1…2147483647
0: Topic inactive, no items are updated. Data acquisition is stopped.
>0: Expected updated interval for the set of all items in the device group
