Hello, I am looking to display specific parameters such as "HomeSpeed" for an axis on the HMI, even though there is no tag linked to each parameter. I am wondering if there is a method to link an axis's parameter to a tag for easy retrieval or adjustment. I am currently utilizing Logix Designer Version 30 for this task. Thank you.
The availability of tags in an axis setup depends on your specific requirements. Some default tags, like commanded Position and actual Position, are readily available. Others, such as torque, can be configured as cyclic parameters within the axis, but they are read-only. Additional parameters like Home related position and speed can be accessed through GSVs and adjusted using SSVs. Certain parameters, like motor temperature, can be retrieved using MSG instructions.
Thank you so much for your help. My goal is to display various parameters on the HMI, such as Homing Speed, Actuator Scaling, Velocity Limit, and Acceleration Limit. Currently, I have these values displayed as "Read only" on the HMI for informational purposes. However, I am concerned because these values are manually inputted and may not always reflect the actual values. If these values change in the future and are not updated in the system, the HMI will display incorrect information. To address this issue, I plan to utilize the GSV instruction and run it at startup to ensure the most up-to-date values are being displayed. Thank you for your assistance.
Success! The GSV tutorial was a complete success. Goodbye.
In Logix Designer, you could leverage User Defined Data Types (UDTs) to create a structure where your "HomeSpeed" parameter or other specific parameters could have corresponding tags. All you'd need to do is create a UDT, add your desired parameters, then create a tag using this UDT. That way, whenever you need to retrieve or adjust the "HomeSpeed", you can do it through a tag linked to it. This provides a very clean and structured approach to managing such parameters.
It seems like you might be able to accomplish this via User-Defined Data Types (UDT). You could create a UDT that includes "HomeSpeed" as a parameter, along with any other parameters you're interested in. Then, for each axis, create an instance of your UDT. This way, your parameters would all be grouped together intelligently in the tag database, and you could then easily link these to your HMI. It might take some time to set up initially, but it could save you a lot of time in the long run.
Sure, in Rockwell's Logix Designer, you can use GSV (Get System Value) and SSV (Set System Value) instructions to access parameters that don't have their own tags. You can use these instructions to create a connection between the parameter ("HomeSpeed" in your case) and a tag you create. When you set this up, every change in the parameter will automatically reflect in the tag and vice-versa. Just make sure you target the correct attribute names in your commands, as incorrect attribute names can cause errors.
It sounds like you're in a bit of a tricky situation without direct tags for those parameters! One approach you could try is using indirect addressing by creating a temporary tag that represents the "HomeSpeed" value. You can then use this temporary tag in your HMI display, which allows you to retrieve and adjust the value more easily. Additionally, consider looking into using UDTs (User-Defined Types) if they fit your application; that way, you could bundle all your related parameters together for better management. Hope this helps!

Answer: 1. How can I link an axis parameter to a tag in Logix Designer for easy retrieval and adjustment? - To link an axis parameter like "HomeSpeed" to a tag for easy retrieval and adjustment in Logix Designer, you can utilize the software's functionality to create connections between the axis parameters and corresponding tags.
Answer: - Certainly! To link axis parameters to tags in Logix Designer for easy retrieval and adjustment, you can follow these steps: 1. Open your Logix Designer project. 2. Navigate to the axis configuration settings. 3. Look for the option to link parameters to tags. 4. Create connections between the desired axis parameters (e.g., "HomeSpeed") and the tags you want to use for retrieval and adjustment.
Answer: - Yes, it is possible to display specific axis parameters like "HomeSpeed" on the HMI without having individual tags for each parameter by linking the axis parameters directly to tags within Logix Designer.
Answer: - The functionality to link axis parameters to tags for easy retrieval and adjustment is available in Logix Designer Version 30 and potentially in other versions as well. It is recommended to check the specific
