SMP Gateway User Manual • 81
Note: As all data points are always made available by an Interconnection slave
instance, the slave’s configuration does not need to be updated when a master’s
configuration is modified (for example, when a data point is added/removed) or
even when a new master is added to the SMP Gateway configuration.
12.2 Configuring the Master SMP Gateway
Now that you have configured the slave SMP Gateway as an Interconnections slave, you will
configure the master SMP Gateway as an Interconnections master. Follow these steps:
Open SMP Manager.
Select the master SMP Gateway (in the example, the Park Avenue SMP Gateway).
From the Tools menu, select SMP Config.
Configure the Interconnections master:
In SMP Config, under Master Protocols, select Interconnections.
In the right pane, under Name, type the slave SMP Gateway's name (in our example,
Cedar Creek), and then click again the Interconnections branch.
A new branch will appear under Interconnections, named after what was just typed.
Expand it and select the General branch.
In the right pane, under Device Prefix, type the prefix that will precede the name of all
data points gathered by the Interconnections master, to distinguish them from the data
points of other masters that may be configured on the same SMP Gateway. For example,
you can type PA_, where PA stands for Park Avenue, the example’s master
SMP Gateway.
Note: The device prefix should be as short as possible, to respect the maximum
length allowed for data points.
Under Client Name, type the same name you specified in the clients list of the
Interconnections slave (in this example, Park Avenue).
Import the slave SMP Gateway’s data points in the master’s configuration:
From the Tools menu, select Import Points from File.
Select the configuration file for the slave (ex. Cedar Creek SMP Gateway's file would be
Cedar Creek.par), and then click Open.
The Update Data Points dialog box will appear, listing all the possible data points that
can be "interconnected".
