Siemens 6AV6372-2DF37-0AH0 SIMATIC WinCC

SKU: 6AV6372-2DF37-0AH0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6372-2DF37-0AH0 is a WinCC (Windows Control Center) runtime or configuration software package belonging to Siemens' SIMATIC HMI software family. WinCC is a PC-based SCADA and HMI software platform designed for process visualization, data acquisition, and operator control in industrial automation environments. This specific part number corresponds to a WinCC software license or upgrade package within the SIMATIC HMI product line.

WinCC offers a comprehensive set of features including tag-based licensing, OPC DA/UA server and client functionality, integrated historian for process data archiving, alarm and event management, and support for scripting via VBScript and ANSI-C. The software integrates natively with Siemens SIMATIC S7 PLCs via MPI, PROFIBUS, and Industrial Ethernet (TCP/IP), and supports a wide range of third-party communication drivers. It runs on standard Windows operating systems and provides a multi-user engineering environment with role-based access control.

WinCC is widely deployed in process industries such as chemical, pharmaceutical, water and wastewater treatment, food and beverage, and energy management. It is also used in discrete manufacturing for machine monitoring, production data collection, and supervisory control. Its scalability from single-station installations to distributed multi-server architectures makes it suitable for both small machine-level HMI applications and large plant-wide SCADA systems.

Common Error Codes & System Events

Event ID: 1000001: Connection to PLC lost or communication timeout on a configured channel
Check network cabling and switch configuration. Verify PLC is powered and in RUN mode. Check channel parameters in WinCC Tag Management.
Event ID: 1000002: Tag read/write error — the specified tag could not be accessed on the controller
Verify the tag address is correct in WinCC Tag Management. Confirm the PLC data block or memory area exists and is accessible.
Event ID: 1000003: License not found or license count exceeded for the configured number of power tags
Check the installed license using the Siemens Automation License Manager (ALM). Install or transfer the correct WinCC license matching the required tag count.
Event ID: 1000004: Archive database error — historian cannot write process values to the archive
Check available disk space on the archive drive. Verify SQL Server service is running. Review archive configuration in WinCC Explorer.
Event ID: 1000005: User administration error — login failed or user account locked
Check user account settings in WinCC User Administrator. Reset the account or unlock the user. Verify OS-level permissions if using Windows authentication.
Event ID: 1000006: Script runtime error — a VBScript or C-script action has encountered an execution error
Open the WinCC Script Diagnostics tool. Review the script log for the offending line. Correct the script logic or variable references in the Graphics Designer.
Event ID: 1000007: Redundancy switchover event — active server has switched from primary to standby
Investigate the cause of the primary server failure. Check system event logs on the primary server. Restore the primary server and perform a manual switchback if required.

Frequently Asked Questions

What is the tag capacity of the 6AV6372-2DF37-0AH0 WinCC license?

The exact power tag count for this specific part number should be verified against the Siemens WinCC ordering data, as the 6AV6372 series covers multiple license tiers. Common tag counts in the WinCC range include 128, 512, 2048, 8192, and 65536 power tags.

Which Windows operating systems are supported by this WinCC version?

WinCC packages in the 6AV6372 series are compatible with Windows 7 Professional/Ultimate (64-bit) and Windows Server 2008 R2, depending on the specific version. Newer WinCC versions also support Windows 10 and Windows Server 2016/2019; check the Siemens compatibility matrix for the exact OS support for this part number.

Can WinCC communicate with non-Siemens PLCs?

Yes, WinCC supports OPC DA and OPC UA interfaces, as well as a wide range of third-party communication drivers, allowing connectivity to PLCs from Allen-Bradley, Schneider Electric, Mitsubishi, and other manufacturers.

Is a SQL Server license required separately for WinCC?

WinCC includes a bundled Microsoft SQL Server runtime edition for its internal historian and alarm archiving functions, so a separate SQL Server license is not required for standard WinCC operation.

Can this WinCC license be transferred to a different PC?

Yes, WinCC licenses are managed through the Siemens Automation License Manager (ALM) and can be transferred to another PC using a USB dongle or via software-based license transfer, subject to Siemens licensing terms.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC license is present and not expired or over-counted.

Install the correct WinCC license matching the required power tag count. Transfer the license from a USB dongle or contact Siemens for license recovery if the host PC has failed.

PLC tags show invalid or no values in WinCC Runtime

Check the channel diagnostics in WinCC Tag Management. Verify the communication driver status and confirm the PLC IP address, rack, and slot settings are correct.

Correct the connection parameters in the WinCC channel configuration. Ensure the PLC is reachable via ping on the network. Restart the WinCC channel driver if the connection was interrupted.

Process data is not being archived and historian gaps appear

Check the SQL Server service status in Windows Services. Verify available disk space on the archive partition and review the WinCC archive configuration for errors.

Restart the SQL Server service if it has stopped. Free up disk space or redirect the archive to a larger volume. Reconfigure the archive cycle and compression settings in WinCC Explorer if necessary.

Alarm system is not logging or displaying alarms in Runtime

Check the WinCC Alarm Logging editor to confirm alarm tags are correctly configured and connected to valid PLC addresses. Verify the alarm server is running in the WinCC project.

Correct any invalid tag references in Alarm Logging. Ensure the alarm archive database is accessible and not full. Restart the WinCC Alarm Logging runtime component via the WinCC project manager.

Graphics screens load slowly or display rendering errors in Runtime

Check CPU and RAM utilization on the WinCC server or client PC. Identify any graphics objects with high update rates or complex scripts that may be causing performance bottlenecks.

Optimize graphics by reducing unnecessary update cycles on dynamic objects. Simplify or offload heavy scripts. Ensure the PC meets the minimum hardware requirements for the installed WinCC version and tag count.
