Freeze Start Type
The Freeze Start Type parameter will define when the module starts sending the
M_IT messages.
Example I – Freeze Start Type
If the module powers up with the following date and time clock:
03/25/2004 18:07:42
If you configure the Interval For Freeze parameter as follows:
Interval For Freeze : 15 #Number of seconds after start
#type (0 to 65535)
The module would send the counter messages every 15 seconds. The module
would start sending the messages depending on the Freeze Start Type
parameter as follows:
Freeze Start Type Time to Start Sending Messages
D 03/26/2004 00:00:00
H 03/25/2004 19:00:00
M 03/25/2004 18:08:00
Example II – Freeze Start Type
If the module should send the counter points on the hourly turn around time and
also 45 minutes later, the Mode A parameters should be configured as follows:
Freeze Start Type : H #D=Day, H=Hour, M=Minute, N=Not
#used
Interval For Freeze : 2700 #Number of seconds after start
#type (0 to 65535)
So the module would send events as follows (Hours:Minutes:Seconds):
17:00:00
17:45:00
18:00:00
18:45:00
19:00:00
19:45:00
…
Mode D
To select the Mode D. configure the Freeze Start Type parameter as "N". For this
mode the master would periodically send Counter Interrogation Commands to
perform the freeze operation. After the values are frozen the module will return
the counter points as events. The counter points must be properly configured for
counter interrogation groups for Mode D operation.
