Configuring Connections
You can configure a connection’s service type, change the priority assigned to the connection for
writing updated values to the target data point, and control whether updates to the source data point are
transmitted to the target data point. To configure a connection, follow these steps:
1. Click Driver.
2. Select one or more of the target data points under the source data point in the SmartServer tree.
To configure one Web connection, click the target data point in the Web connection to be
configured. To configure two or more Web connection, click one target data point and then either
hold down CTRL and click all other target data points in the Web connections to be configured or
hold down SHIFT and select another target data point to configure the Web connections
represented by the entire range of selected target data points.
