ClearSCADA

Please read the information below prior to installing ClearSCADA 2017 R2 for important information on any known issues.

Licensing

As in the previous release, ClearSCADA 2017 R2 will require one Data Access license per system from each ‘active’ ClearSCADA server connected to the IIS instance. By ‘active’ this means the connected server of the redundant connection setup. This is independent of the number of users connected to IIS, and is part of your ClearSCADA Server license.

ClearSCADA 2017 R2 will also require one WebX client license per logged-in user from each ‘active’ ClearSCADA server connected via the IIS instance. By ‘active’ this means the connected server of the redundant connection setup. The WebX client licenses you purchase and install on a server can be used simultaneously with Original WebX (where the usage is shown in the Server Status tool) and the IIS WebX (where the usage is logged in the WebX.log file).

While additional users above your licensed limit per server can be logged-in, using either Original WebX and IIS WebX simultaneously or using multiple separate IIS WebX instances, this is a transition for licensing and you are expected to purchase licenses equivalent to your usage. Future releases of ClearSCADA are expected to enforce license limits. This will be highlighted in Release Notes.
