The module will periodically send all points configured for periodic/cyclic poll
(0x80000000) at every x milliseconds, where x is configured with the following
parameter:
Cyclic data transmission: 20000 #Numb of milliseconds between cyclic
#updates
Example – Periodic Monitor Polling:
If the following point is configured for monitor polling:
[M_ME_NB_1]
#
# Each point is one word and the DB Address value corresponds to the
# word offset into the database.
#
# Default
# Point # DB Address Group(s) Deadband IV DB Bit
# ------- ---------- -------- -------- ---------
START
100 0 80000000 0 0
END
If you configure the periodic polling for 10 seconds (10000 milliseconds) as
follows:
Cyclic data transmission : 10000 #Numb of milliseconds between
#cyclic updates
The following illustration shows the communication procedure:
Therefore, the point configured for a cyclic poll is periodically reported to the
master.
You may also create groups of points allowing the master to poll certain points
more frequently than other points. The master may send requests for different
groups as follows:
General Interrogation (station)
General Interrogation for Group 1
