Siemens SCADA software titles within the SIMATIC portfolio are engineering and runtime platforms designed for industrial process visualization, data acquisition, supervisory control, and web-based operator access. The collection spans four product families: SIMATIC WinCC/CAS upgrade licenses for Central Archive Server migrations, SIMATIC Process Historian packages for long-term production data archiving, SIMATIC Information Server upgrade licenses for plant-wide reporting infrastructure, and SIMATIC WinCC/WebUX client access licenses for web-based operator interfaces. These are software-based tools for building, managing, and archiving the visualization layer of an automation system, not standalone hardware.
PLC Direct supplies Siemens SCADA software licenses and packages to customers replacing or upgrading visualization infrastructure in existing SIMATIC installations. Our collection covers SIMATIC WinCC/CAS, Process Historian, and Information Server upgrade titles, as well as WinCC/WebUX client access licenses across multiple tier sizes.
Where Siemens SCADA Software Is Used
A missing or corrupted WinCC license in an active production environment can bring visualization and historian functions offline, leaving operators without process data and maintenance teams without a clear path to diagnosis. At enterprise and multi-site scale, centralized archiving and CAS infrastructure become a single point of failure when replacement licenses are unavailable on short notice, and OEM procurement channels can involve long lead times for older software versions.
Facilities that depend on Siemens SCADA software include:
-
Process manufacturing plants running SIMATIC WinCC for continuous process visualization and alarm management
-
Facilities using SIMATIC Process Historian for long-term production data archiving and compliance reporting
-
Multi-server installations relying on WinCC/CAS for centralized archive management across distributed production sites
-
Operations requiring runtime upgrades from earlier WinCC versions to maintain compatibility with current SIMATIC S7 hardware
-
Utilities and infrastructure installations where loss of visualization access creates regulatory and operational risk
When a license or upgrade package needs to be sourced quickly to restore or maintain a running SCADA environment, having available stock outside standard OEM channels reduces the window of disruption.

What to Know Before You Buy Siemens SCADA Software
Sourcing the correct WinCC, Process Historian, or Information Server license requires matching the software title, the source version being upgraded from, and the target version. Ordering the wrong upgrade path will result in a license that cannot be applied to the installed software version. For WinCC/WebUX, the key variable is the client count required for the deployment.
Version compatibility: WinCC/CAS and Process Historian upgrade titles are version-specific. The source version installed on the server must match the upgrade path defined in the license part number. Confirm the currently installed WinCC or Process Historian version before ordering.
Delivery format: Products in this collection are delivered in two formats. Physical delivery titles (6AV6361-1AA01-4AE0) include DVD media and a USB flash drive with the license key. Download delivery titles require a valid consignee email address at the time of order, as the license key and software access are sent digitally. Confirm the preferred delivery method and ensure an email address is available for downloading titles before placing an order.
WinCC/WebUX client tier selection: WinCC/WebUX client licenses are counted and sized by concurrent client access. Available tiers in this collection are 1, 3, 10, 30, and 100 client licenses. Select the tier that matches the number of concurrent browser-based operator sessions required. WinCC/WebUX requires a 64-bit Windows server environment and a base WinCC V7.3 or WinCC Professional V14 or higher license.
Lifecycle status: WinCC/CAS, Process Historian, and Information Server titles in this collection carry PM400 (Announcement of product phase-out) lifecycle status. These are legacy software titles for maintaining existing installations. WinCC/WebUX titles carry PM300 (Active Product) status and remain in current production.
Warranty: All Siemens SCADA software products purchased from PLC Direct include a standard 1-year warranty covering defects and functionality.
