10.4 Configuring the Data Points
The slave component automatically converts the subscribed data points to the appropriate format
for the protocol. However, you should make sure the default settings are appropriate and perform
any necessary adjustments.
To configure the data points:
In the left pane, click the data point type, to display a list of all the data points and their
settings.
There are different settings for each protocol. However, you should at least check the address
or index assigned to each data point.
For instance, the following settings are provided for a DNP3 data point:
Each data point is automatically assigned an Index value according to the subscription
order. You should ensure that these index values correspond to those expected by the
control center.
The Event Class setting groups data points together for subsequent reporting to the
control center.
10.5 Configuring the Communications Links
We previously described how to configure a serial communications link for a master protocol
component. The procedure is identical for a slave protocol component that uses a serial
communications link. However, a slave protocol component typically uses a TCP/IP connection
over a LAN, to communicate with the control center. For more information about communications
link configuration, see “Configuring the Communications Links”, page 34.
10.5.1 Setting up a TCP/IP Slave Connection
To configure a TCP/IP connection for a slave protocol component:
In the left pane, under Connections, click TCP/IP Slaves, to display the list of defined
connections.
Enter the settings for the new TCP/IP connection in an empty row of the grid:
Specify a significant name for the connection.
Specify the TCP port number to be used.
10.6 Associating a Slave Protocol Instance with a
Communications Link
You now have to identify the communications link which will be used by the slave component to
communicate with the control center.
