How Freeze Start Type Affects M_IT Message Transmission
Assume the gateway powers up with a date and time of: 03/25/2004 18:07:42.
The gateway would send the counter messages every 15 seconds. The gateway
would start sending the messages depending on the Freeze Start Type parameter
as follows:
Freeze Start Type
Time to Start Sending Messages
Day 03/26/2004
00:00:00
Hour 03/25/2004
19:00:00
Minute 03/25/2004
18:08:00
How Freeze Start Type and Interval for Freeze Affects M_IT Message Transmission
Assume the gateway powers up with a date and time of: 03/25/2004 18:07:42.
If the gateway should send the counter points every hour, on the hour and send
them again 45 minutes later, the
Freeze Start Type
parameter should be set to
H
OUR
and the
Interval for Freeze
parameter should be set to
2700
(seconds), as
shown:
With these setings, the gateway would send counter events as follows
(Hours:Minutes:Seconds):
18:45:00
19:00:00
19:45:00
20:00:00
20:45:00
...and
so
on..
