specified minimum time.

configuration was changed or removed since it was last imported.

10.8 Manage Connections
10.8.1 Create a New Connection
After configuring the device’s data points, internal connections between those data points
can be made using local connection objects.
A connection is an internal mapping in the device between input and output data points. A
connection always consists of one or more data points. A value update from an input data
point is distributed to all output data points. A status change of an output data point is
propagated back to all input data points. All data points in the connection must be of
compatible type.
To create a new connection
1.
Click on the
Local Connections
tab in the data point configuration window and press
the button
Create new Connection
.
In the menu choose
Standard Connection

connection list. Rename the connection if you want to do so.
2.
Above the list

on the right-hand side click on
Attach
Data Point
to add data points for this connection. This opens a list of all available data
points. Select one and press
OK
. You may use multi-select to select more than one
data point at a time.
