1.1.21 [C_SE_NC_1 104] Section
This section defines the short-float setpoint database for the server emulated.
This information is sourced from the remote client and is transferred to the
database. Each point occupies a double-word position in the database. If the
Require Select parameter is not set to zero, a select command must be received
before an execute command will be processed.
This section takes the following parameters:
Point #:
DB Address:
Monitor Point #:
Monitor
DB Addr:
Require Select:
Each point is two words and the DB Address value corresponds to the double-
word offset in the database.
The database address should be located in a database area that is being
constantly moved from the module to the processor. You should configure the
DB Address parameter in an area that is on a Backplane Command Function 2.
1.1.22 Group Definition
One aspect of the point configuration database that leads to confusion is the
group definition field. This assignment for each point assigns a 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:
