see Status Data Object (page 57).
The following illustration presents one of many possible combinations of these
flexible configuration options.
In this example, Port 0 on the module communicates with 4 sessions (0, 1, 3, and
4), each of which has their own data set(s). Session 1 has only one sector (all
data for this one device contained in a single database). This sector is addressed
by the Master using the Common Address of ASDU value set for the sector in the
configuration file. Session 0 contains two sectors, each with their own unique
Common Address of ASDU value to identify the sector.
Port 1 is connected to one device on the network. This device is defined in the
Session 2 section of the configuration file. In this example, all data from this
device is stored in a single sector.
