Licensing

Citect SCADA supports two different software licensing models:

Sentinel Licensing (using USB keys)

Sentinel Licensing is a legacy licensing solution for Citect SCADA. It uses physical USB keys that plug in to each computer in your Citect SCADA system. The USB key contains details of your user license, such as its type and I/O point count.

You are occasionally required to update your Sentinel keys, for example, when you upgrade to a new version of Citect SCADA. To do this, you need to retrieve an authorization code from Schneider Electric's online License Generator. See Update a Sentinel Key with CiUSAFE.

FLEXERA Softkey Licensing

The FLEXERA softkey solution stores license information on a FlexNet Enterprise License Server. The Citect SCADA client process will retrieve licenses from this server as required by the Citect SCADA system. To activate and administer licenses, you use the Floating License Manager (see Activate Licenses Using the Floating License Manager).

In both cases, Citect SCADA uses a Dynamic Point Count to determine if your system is operating within the limitations of your license agreement. This process tallies the number of I/O device addresses being used by the runtime system.

A point limit is allocated to each type of license included in your license agreement. These license types include:

• Full Server Licenses
• Control Client Licenses
• View-only Licenses.

A special OPC Server License is also available if you want to run a computer as a dedicated OPC server. For more information, contact Technical Support.

If required, you can specify how many points will be required by a particular computer (see Specify the Required Point Count for a Computer).

Note:
• There is no distinction between a Control Client and an Internet Control Client.
• There is no distinction between a View-Only Client and an Internet View-Only Client.
