Key Takeaway
STEP 7 and TIA Portal are related but not the same. STEP 7 is the traditional software used for programming Siemens PLCs like the S7-300 and S7-400. It existed as a standalone tool before the TIA Portal concept. The TIA Portal, on the other hand, is a modern, integrated engineering environment where STEP 7 has been embedded along with other tools like WinCC (for HMIs) and StartDrive (for Drives). In TIA Portal, STEP 7 functions as a module for PLC programming. So while STEP 7 exists independently (older version) and inside TIA Portal (new version), TIA Portal itself offers a broader, unified development experience beyond just PLC programming.
Understanding STEP 7 as a Software Component
To put it simply, STEP 7 is a classic software suite designed by Siemens for programming and configuring Siemens PLCs. It has been a staple in the industrial automation world for many years. For engineers, STEP 7 was the go-to tool for programming, monitoring, and configuring automation systems. It supports PLC hardware setups, creates control logic programs, and allows for effective communication between various automation devices.
However, STEP 7 on its own can seem a bit limited compared to modern demands in the automation industry. While STEP 7 provided great functionality in its time, it was mainly focused on the PLC programming aspect, with limited support for newer devices or multi-discipline automation systems.
So, while STEP 7 has been a reliable tool for many years, it’s no longer the top choice when it comes to versatility and integration with other systems. This is where TIA Portal steps in.
Classic STEP 7 vs TIA Portal Integration
Now, the TIA Portal (Totally Integrated Automation Portal) takes everything STEP 7 did well and improves upon it. Unlike STEP 7, TIA Portal is an integrated engineering framework designed to streamline your work process. The major difference lies in how these tools operate.
With TIA Portal, Siemens has brought a one-stop platform that integrates not just PLC programming but also other automation tasks such as motion control, HMI (Human-Machine Interface), and SCADA systems. It combines multiple tools under one roof, making it easier for engineers to design and manage automation projects in a more holistic manner.
So, what does this mean for you as an engineer? If you’re still using STEP 7, you’re missing out on the efficiency and integration offered by TIA Portal. TIA Portal allows you to work with a wider range of automation equipment, from PLCs to HMIs, and even industrial robots. The integration across different engineering disciplines within a single software suite greatly reduces the time it takes to set up and maintain automation systems.
Feature Set Differences
One of the most significant differences between STEP 7 and TIA Portal is the range of features they offer. In a nutshell, TIA Portal brings a host of additional functionalities that STEP 7 simply doesn’t provide.
User Interface: While STEP 7 had a more basic user interface, TIA Portal features a much more modern, user-friendly interface. This makes it easier for you to navigate the tool, find functions quickly, and set up your systems with less hassle.
Integrated Diagnostics: With TIA Portal, diagnostics are integrated into the software environment, making it easier to troubleshoot and resolve issues. You can access detailed information about the system status, which is crucial for identifying faults in your automation setup.
Multi-Discipline Integration: As we mentioned earlier, TIA Portal is not just for PLC programming. It supports a range of automation technologies including motion control, drives, HMI, and more. STEP 7, on the other hand, was strictly limited to PLC programming.
Simulations and Virtual Commissioning: TIA Portal also includes more advanced simulation features. You can virtually simulate the behavior of your systems, making it easier to test and validate before physical deployment.
Cross-Platform Compatibility: Another impressive feature of TIA Portal is its ability to support multiple hardware platforms. If you’re working with Siemens PLCs from different series, TIA Portal allows seamless integration and programming across them. STEP 7 was limited in this area.
Supported PLCs in Both Environments
While both STEP 7 and TIA Portal are used to program Siemens PLCs, there’s a clear difference in terms of the PLC models they support.
STEP 7: This software primarily supports older PLC models such as the S7-300, S7-400, and S7-1200. These are still widely used in various industries, but they belong to an older generation of Siemens PLCs.
TIA Portal: TIA Portal supports a much broader range of Siemens PLCs, including the newer S7-1200, S7-1500, and even the S7-1500T series. It’s more future-proof and provides compatibility with cutting-edge PLC technologies that offer higher performance and more advanced features.
As you can see, if you’re working with newer Siemens PLCs, TIA Portal is the clear choice. It’s built to handle the more advanced capabilities of these systems, ensuring that your programming efforts are not limited by outdated software.
Transitioning from Classic to TIA Portal
So, you’ve been using STEP 7 for years, and now you’re thinking about upgrading to TIA Portal. The transition might seem a bit daunting at first, especially when you’ve gotten used to the older software. However, once you familiarize yourself with TIA Portal’s interface and capabilities, the benefits become clear.
Ease of Use: The first thing you’ll notice is the ease of use. TIA Portal’s interface is more intuitive, with easier navigation and better workflow management. Once you’ve set up a few projects, you’ll appreciate the streamlined process and reduced complexity compared to STEP 7.
Backward Compatibility: Don’t worry about losing your old projects. TIA Portal offers backward compatibility with STEP 7 projects. This means you can import existing STEP 7 projects into TIA Portal without starting from scratch. This makes it easier to transition, especially if you’re working with legacy equipment.
Training and Support: While transitioning to a new platform always requires some training, Siemens provides ample resources. With online tutorials, documentation, and support forums, you’ll be up to speed in no time.
The upgrade from STEP 7 to TIA Portal might require some initial time investment, but in the long run, it’s an investment that will make your work as an automation engineer much more efficient and productive.
Conclusion
In conclusion, while STEP 7 served as a strong foundation for Siemens PLC programming, TIA Portal takes things to the next level by offering a fully integrated platform with a host of advanced features. It supports a wider range of PLCs, offers better diagnostics, and integrates various automation disciplines under one roof. If you’re still using STEP 7, it might be time to make the switch to TIA Portal for a more seamless, efficient, and future-proof automation experience.
The transition may seem challenging at first, but once you experience the benefits of TIA Portal, you’ll understand why it’s the preferred choice for modern automation projects.
