For engineers and automation professionals using Siemens WinCC SCADA, data logging is essential for monitoring, analysis, and compliance. While Excel is a common tool for exporting and managing WinCC data, many scenarios call for alternatives that do not rely on Excel software. This list covers 10 practical methods to log and handle WinCC SCADA data without using Excel, providing options for diverse system requirements and environments.
1. Native WinCC Data Logging with Tag Logging
WinCC offers built-in tag logging functionality that records process values directly into its own archive or SQL databases. This method eliminates the need for Excel by storing data in formats accessible via SQL queries or WinCC’s internal archive viewers. It is efficient for historical data tracking and can be configured to log data at custom intervals or event triggers.
2. Using SQL Server Directly for Data Storage
Instead of exporting to Excel, WinCC can log data directly into Microsoft SQL Server databases. This approach leverages WinCC’s ODBC or native SQL interfaces to write data in real-time. Users can then access and analyze data using any SQL-compatible tool or custom applications, bypassing Excel entirely.
3. CSV File Export via WinCC Scripting
WinCC scripting (VBScript or C scripts) can automate data exports to CSV files, a widely supported plain-text format. CSV files are lightweight and can be read by many applications without Excel. Scripts can be scheduled or triggered by events to create logs that are easy to share or import into alternative data analysis software.
4. OPC UA Data Logging with Third-Party Tools
WinCC supports OPC UA, a standardized industrial communication protocol. By connecting WinCC to third-party OPC UA clients that include data logging features, users can capture and store SCADA data without Excel. Popular OPC UA logging tools include Matrikon OPC Logger and Unified Automation’s UaExpert with logging plugins.
5. Integration with Historian Systems Like OSIsoft PI
WinCC data can be routed to industrial historian platforms such as OSIsoft PI System, which specialize in high-performance data logging and retrieval. These systems offer robust data compression, querying, and visualization capabilities that do not require Excel. This method is ideal for large-scale operations needing long-term data management.
6. Use of WinCC OA (Open Architecture) for Flexible Data Handling
WinCC Open Architecture (OA) provides a flexible platform for custom data logging solutions. It supports various database backends and file formats, enabling users to implement logging without Excel dependencies. OA’s scripting and API allow tailored data workflows suitable for complex or non-standard logging requirements.
7. Exporting WinCC Data to XML Format
WinCC supports exporting data in XML format, a structured and widely accepted data exchange standard. XML exports can be automated through scripting and consumed by numerous software platforms for reporting or archiving. This format is especially useful when integrating with enterprise systems or web services without Excel.
8. Using OPC DA with Custom Data Logger Applications
For setups still using OPC DA (Data Access), custom applications can subscribe to WinCC data points and log values into databases or flat files. Developers can create lightweight logging tools in languages like C# or Python, enabling flexible, Excel-free data management tailored to specific project needs.
9. Cloud-Based Logging via MQTT Integration
WinCC can be integrated with MQTT brokers using middleware or gateway solutions. This allows SCADA data to be published to cloud platforms or on-premises MQTT servers, where it can be logged and analyzed with cloud-native tools such as Grafana or InfluxDB. This modern approach avoids Excel and supports scalable, remote data monitoring.
10. Utilizing WinCC Runtime Logging Features
WinCC Runtime includes built-in logging features that can capture alarms, events, and process values directly to internal logs or text files. These logs can be accessed and processed without Excel, providing quick access to operational data for troubleshooting or compliance verification.
How to Choose
When selecting a method for WinCC SCADA data logging without Excel, consider your existing infrastructure, data volume, and analysis needs. If you require long-term storage and complex queries, SQL Server or historian systems like OSIsoft PI are preferable. For lightweight or ad hoc logging, CSV or XML exports are simpler and more portable. Integration capabilities (e.g., OPC UA or MQTT) matter if you plan to connect to external systems or cloud platforms. Also, consider your team’s expertise; scripting and custom applications offer flexibility but require programming skills. Finally, ensure that the chosen method aligns with your data security and compliance requirements.
Frequently Asked Questions
Can WinCC log data without any database?
Yes, WinCC can log data directly into its internal archive or as flat files like CSV or text without using an external database.
Is it possible to automate data export from WinCC without Excel?
Absolutely. WinCC scripting allows automated exports to CSV, XML, or other file formats on schedules or events, removing the need for Excel.
What is the advantage of using OPC UA for data logging?
OPC UA provides a standardized, secure, and platform-independent way to access and log data, enabling integration with many third-party tools beyond Excel.
Can I use cloud services to store WinCC data?
Yes, by integrating WinCC with MQTT or other middleware, you can forward data to cloud storage and analytics platforms without Excel involvement.
Does using SQL Server mean I cannot use WinCC internal archives?
No, you can use both simultaneously. SQL Server offers more flexibility for complex queries, while internal archives are optimized for WinCC’s native functions.
Is scripting necessary to avoid Excel in WinCC data logging?
Not always, but scripting enhances automation and flexibility for exporting data in formats other than Excel-compatible files.
Final Thoughts
Logging WinCC SCADA data without relying on Excel is not only feasible but often advantageous in industrial environments. Whether you prefer direct database logging, file-based exports, or integration with cloud and historian platforms, multiple reliable options exist. Selecting the right approach depends on your operational needs, scalability, and technical resources. Exploring these alternatives can improve data accessibility, security, and analysis beyond the limitations of Excel.
