Can someone provide clarification on the significance of the number in the connection tag and tips on locating this tag within the connected PLC? Your help is greatly appreciated.
When working with a "global object," it is important to understand the parameters as they serve as placeholders for reusing objects. To view the tags that replace these parameters, right click on the containing group and select "Global Object Parameter Values." You may need to navigate up one or more levels to locate the containing group. Understanding and utilizing these parameters can help optimize object reusability in your project.
A placeholder is a common tool used in conjunction with a parameter file to dynamically load a specific tag when a display is triggered. To identify the tag being loaded, examine the properties of the button calling the display and locate the item specified in the Parameter File field. Within the Explorer window, navigate to the Graphics folder and find the "Parameters" item. Search for the parameter file mentioned in the button's settings and locate the line "#123 = " to uncover the tag name being inserted into the object during display activation. While placeholders are often used with Global Objects, they can also be utilized with other types of objects. In the example provided, there are no clear indications of a Global Object, but further investigation may reveal additional insights.
The global object is designated for parameters exceeding 100 in number. Rockwell suggests utilizing #1-99 for items replaced by /P or /T. While the decision is ultimately left to the author, following this recommendation can streamline operations due to the presence of a single "parameter symbol table" per display.
In a recent discussion, Cheeseface pointed out the use of global objects due to having over 100 parameters. Rockwell suggests sticking to numbers 1-99 for items replaced by /P or /T. Although it's ultimately up to the author, this method simplifies things by having only one "parameter symbol table" per display. This information was new to me, but it definitely makes sense. OG
I have located the information, thank you for sharing - it is greatly valued.
The number in the connection tag usually represents a specific address or identifier for that connection, which helps in distinguishing it from other tags in the PLC. This is crucial for troubleshooting and ensuring that the right data is being accessed. To locate this tag, you can usually find it in the PLC programming software under the connections or I/O configuration section. Just make sure you’re looking at the correct module or network interface where the connection is established!
The number in the connection tag is crucial as it usually indicates the specific data connection or protocol being used, helping you identify which tags correspond to each PLC's communication. To find this tag within your PLC, check the documentation for the specific model you’re working with, as it often includes a mapping of connection numbers to their respective functions. Additionally, exploring the PLC’s programming software can offer a visual representation, making it easier to locate and understand how the connections are structured. If you have access to previous projects, they might also provide insights into how tags were organized in similar setups.
