Each point is one 16-bit word and the DB Address value corresponds to the word
offset in the module memory database. For additional information on how to set
these parameters, see the Reference chapter of this manual.
5.24 [C_SE_NC_1 104]
This section defines the short-float setpoint database. This information is sourced
from the remote Client and is transferred to the database. If the Require Select
parameter is set to one (1) or Y
ES , a Select command must be received from the
Client before an Execute command from the Client will be processed.
This section takes the following parameters:
 Point #
 DB Address
 Monitor Point #
 Monitor DB Address
 Require Select
Each point is two 16-bit words and the DB Address value corresponds to the
double-word offset in the module memory database. For additional information
on how to set these parameters, see the Reference chapter of this manual.
5.25 Group Codes
One aspect of the point configuration database that leads to confusion is the
group definition field, which assigns each point to one or more interrogation
groups. Use of interrogation groups permits the controlling unit to interface with a
specific set of data. Refer to the IEC 60870-5-104 standard for a full discussion
of interrogation groups. A specific group, Periodic data group, reports data points
on a set frequency. The frequency is set in the Cyclic Data Transmission
parameter in the configuration file. Remember that a point can be assigned to
more than one group.
