C_SE_NC
The measured short floating point command uses two words with double word
addressing.
For example, if you configured the following points:
# DB Address Monitor Monitor Require
# Point # (word*2) Point # DB Addr Select
# ------- ---------- ------- ------- -------
START
400 10 0 0 0
401 12 0 0 0
402 18 0 0 0
END
These points would be used as follows:
Inf. Object Address Module Database Address
400 Words 20 and 21
401 Words 22 and 23
402 Words 24 and 25
2.1.5 Data Communication
Group Communication
As previously discussed, the Group parameter in the module configuration file
controls how each monitored point is transferred between the 4205/5205-TS-
104S-PDPS module and the client unit. The Group parameter is described in
detail in Group Definition (page 30)
The following example configures this point to be repeated either during cyclic
polls, or when the module General Interrogation request for group 1 occurs.
# Point # DB Address Group(s)
# ------- ---------- --------
START
100 1600 80000002 # P1-PSHH -- Discharge pressure SD
END
The module periodically sends all points configured for periodic/cyclic poll
(0x80000000) at the interval in milliseconds configured with the following
parameter:
Cyclic data transmission : 20000 #Numb of milliseconds between cyclic
#updates
You can also divide the monitored points into different groups, allowing the client
to periodically poll only certain points. This also allows some points to be polled
more frequently than others.
Note:
You should configure the counter points (M_IT_NA) for general counter
interrogation or group counter interrogations.
