The SCADA node is the only node in the
system with a Hardkey used for Licensing. Each SCADA node
must have its own Hardkey and matching License software control
file. In the full-feature version, an unlimited number
of clients can connect to a SCADA node (your License may limit this
number). The number of Tags is also limited on a given SCADA
node by the software control license file. For more information
