Example II - Freeze Start Type
If the gateway should send the counter points on the hourly turnaround time and
also 45 minutes later, the Mode A parameters should be configured as follows:
So the gateway 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 gateway will return
the counter points as events. The counter points must be properly configured for
counter interrogation groups for Mode D operation.
Monitor Points Addressing
As discussed before, the monitor points must be configured in a database area in
the PTQ-104S module.
The monitor data types are described in the following table.
Data Type Data Size Addressing Type
M_SP_NA 1 bit Bit
M_DP_NA 2 bits Bit
M_ST_NA 1 byte Byte
M_ME_NA 1 word Word
