Retrieve Step Names in SFC Routine written in Studio5000

Question:

Hello! I am looking to retrieve the names of the steps in a routine written in SFC language within Studio5000. Is there a system variable that can provide me with this information? I have thoroughly searched all the functions of GSV but have been unable to find any relevant details. I am trying to avoid having to manually change a variable for each step in an action, as this process is quite inefficient for me. However, if there are no alternative solutions, I may have to resort to that method. Thank you for your assistance and time. Best regards.

Are you curious to know if anyone has successfully identified this skill? I am eager to receive the detailed guide on how to implement this feature into an HMI system.

Hi there! While I appreciate your desire for efficiency, I'm afraid Studio5000 doesn't have a system variable that can directly retrieve the names of the steps in an SFC routine. An inconvenient truth, I know. You'd indeed have to manually change a variable for each step. It's not ideal but that's the present situation. However, you can use structured text and an array of strings for the step names to help save some work. It's always good practice to keep pushing the boundaries of a system to find the most efficient way! Best of luck with your project.

Hi there! It sounds like you're dealing with a bit of a hassle. While Studio 5000 doesn't have a built-in system variable to directly retrieve step names in SFC, you might consider creating a structured data type that maps your step names to corresponding IDs. This way, you can reference them programmatically without manual updates for each step. Additionally, utilizing functions like GSV in combination with some custom logic could potentially streamline your routine extraction process. Hopefully, this can help you minimize manual effort while keeping your code organized! Good luck!

Hey there! I totally understand how tedious manually changing variables can be. While Studio5000’s SFC doesn’t offer a direct system variable for step names, you could consider using the SFC's built-in methods or leveraging the Add-On Instruction (AOI) to manage step data better. Creating a structured data type that holds step names and then using a loop might streamline your process a bit. It might take some upfront work, but it could save you time in the long run! Hope that helps!

Hey there! I totally understand your frustration with the manual approach. Unfortunately, SFCs in Studio5000 don’t have a built-in system variable that directly retrieves step names efficiently. However, consider using a structured approach with user-defined functions or function blocks to encapsulate the logic and keep your code clean. You could also explore creating a custom routine that builds a list of step names dynamically for you. It might take some initial setup, but it could save you a lot of time in the long run. Good luck!
