Polling
Frequency
[1/10 sec]
For a small number of devices, primarily I/O devices (see
Using
Dedicated I/O Devices
), it is necessary for the surveillance system to
regularly check the state of the devices' input ports in order to
detect whether input has been received.
Such state checking at regular intervals is called polling. The Polling
Frequency field lets you specify the interval between state checks.
Interval is specified in tenths of a second. Default value is 10 tenths
of a second (i.e. one second).
For I/O devices it is highly recommended that the polling frequency
is set to the lowest possible value (one tenth of a second between
state checks).
For information about which devices require polling, see the release
note.
