Enter the license keys for the Device Packs that identify how many devices the server can monitor, and for any applications that need access to information about those monitored devices, at the server.
The MODBUS TCP Output Module and the Surveillance feature are examples of applications that need to have license keys entered at the Data Center Expert server. More information about licenses is available here.
License keys are listed by License Type, the number of devices each license enables the server to monitor (Node Count), and how many of those devices are being monitored (Used Node Count).
Click License Key Details to view information about the selected license key, and copy it into a document.
