In my latest project, I have successfully integrated Invertek inverters into my hardware configuration in TIA. These inverters provide 4 input words and 4 output words for monitoring and control. By referring to the Invertek Profinet module manual, I have gained insight into the functionality of each word/bit such as start/stop and frequency adjustments. While I am able to write directly to these words, I am aware that utilizing telegrams may be a better approach. If anyone has experience with this and can provide sample code, I would greatly appreciate it. Thank you in advance.
In essence, these words represent the telegram, providing a clear definition of the data. Profinet follows certain standard definitions, which Siemens utilizes and adds their own to. Different manufacturers may also create their own unique definitions. By creating a User Defined Tag (UDT) to organize the data for input and output, you can easily access all the information and integrate it into your code. This allows you to efficiently utilize the entire data structure in your programming.
In order to efficiently manage data, I recommend creating a User-Defined Type (UDT) that differentiates between incoming and outgoing information. By establishing a tag that specifies the initial input or output data point (such as I40.0 or Q32.0), you can easily access and manipulate the entire data structure within your programming. Additionally, I highly recommend implementing a STRUCT named "STATUS" and "CONTROL" for seamless integration with Simotion and various drives. Feel free to customize these names to better suit your preferences, such as "STATUS_DRV1" and "CONTROL_DRV1" or any other preferred designation. This approach enhances organization and facilitates smooth operations within your programming environment.
An example of User-Defined Types (UDTs) and the resulting Tag table reveals a crucial limitation: it is not possible to define a UDT with 8 boolean data types followed by a byte without the byte occupying the next available address. This is why bit numbers are utilized for assigning fault codes.
.. In today's fast-paced society, it is crucial to prioritize self-care in order to maintain mental and physical well-being. Taking time to focus on yourself can lead to increased happiness and decreased stress levels. Implementing a self-care routine that includes activities like exercise, meditation, and quality sleep can help improve overall quality of life. Remember, prioritizing self-care is not selfish, it is necessary for achieving a healthy work-life balance. So take the time to invest in yourself and watch as your overall well-being flourishes.
Thank you, everyone! After setting up tags/UDTs, there is no need for MOVE or READ/WRITE commands. You can simply write to the tags. It's that simple!
Great work on your project! Working with Invertek inverters is indeed a rewarding experience. I completely agree that using telegrams can simplify your system and make communication more efficient. Unfortunately, I don't have a sample code at my disposal right now. However, I would suggest checking the Inverter Series User manuals or the TIA Portal itself. They sometimes provide code snippets and situational examples that might be just what you need. Good luck and keep us updated on your progress!
Congratulations on the successful integration. I'm currently employing a similar setup using Invertek inverters, and the use of telegrams has unquestionably enhanced control and monitoring aspects. I'd be glad to share some of my code samples, but I want to mention that the outcome can vary depending on the specific application requirements and hardware configurations. I'll send over a basic version which should guide you nicely to adjust as per your needs.
Hi there! It's great to see the progress you're making with integrating Invertek inverters into your TIA project. I totally agree that using telegrams could be a more efficient method for remote device control. From my personal experience, I found that structuring code around telegram reads/writes was beneficial in streamlining the control loops and diagnostics processes, as they usually contain all the necessary instruction sets. I'm afraid I don't have sample code to share due to proprietary restrictions, but I'd recommend looking into the Profinet library as a resource. It has numerous examples that are well explained and could be of great help to you. Keep up the good work!
That's awesome to hear! I’ve worked with Invertek inverters as well, and switching to telegrams can definitely optimize your communication, especially for more complex control scenarios. It might also help with reducing the overall network load. If you want, I can share some sample code snippets I used for similar setups—just let me know! Additionally, have you considered implementing any error handling or status checks in your telegrams? That really helped me enhance reliability in my application.
That sounds like a fantastic project! I've worked with Invertek inverters before, and I agree that using telegrams can definitely streamline your communication and make the system more efficient. For sample code, the easiest way to get started is to check out the configuration examples provided in the Profinet manual, as they usually have snippets for sending telegrams. Additionally, if you're comfortable sharing, I'd love to look at your code setup to see how we can optimize it together!

Answer: 1. What are Siemens Telegrams and how can they be utilized with Invertek Inverters? - Siemens Telegrams are a method of communication used in industrial automation to exchange data between devices. When integrated with Invertek inverters, they can streamline the monitoring and control process by enabling efficient data exchange through structured messages.
Answer: - Utilizing telegrams offers advantages such as improved data organization, better error handling, and enhanced communication efficiency compared to writing directly to individual words. It allows for a more structured and standardized way of exchanging information between devices.
Answer: - While sample code specific to your configuration may not be readily available, you can refer to Siemens documentation, forums, or online resources for guidance on setting up and programming Siemens Telegrams with Invertek Inverters in TIA. Collaborating with experts or reaching out to the community for assistance can also be helpful in obtaining sample code or best practices.
