Example II - Freeze Start Type
If the gateway powers up with the following date and time settings on its internal
clock:
03/25/2004 18:07:42
And if you configure the Interval For Freeze parameter to 15 seconds, as follows:
The Freeze Start Type parameter determines when the gateway will begin
sending these messages, as follows:
If the Freeze Start Type is set to: Then Messages will start being sent at:
D
03/26/2004 00:00:00 and every 15 seconds thereafter
H 03/25/2004 19:00:00 and every 15 seconds thereafter
M 03/25/2004 18:08:00 and every 15 seconds thereafter
Once message transmission begins, the gateway will freeze and transmit counter
values at whatever interval has been configured using the Interval For Freeze
parameter. In this example, that would be every 15-seconds.
2.1.18 Interval for Freeze
0 to 65535 seconds
Freeze Start Type and Interval for Freeze are used if Mode A operation is to be
used for the counter freeze operation. If they are not used, the gateway will
operate in Mode D.
