Looking for a method to determine if a controller in ControlLogix is online through logic? It might be possible to use a CIP object for querying. Any insights or suggestions are appreciated. Thank you, Trevor.
Are you wondering about the quantity of connections?
I wonder if JeremyM is knowledgeable about this? It is likely.
Examine audit logs for improved visibility and security measure effectiveness. Explore the audit logs on the Rockwell Automation literature website for enhanced insights.
I wanted to steer clear of the audit logs and find a straightforward CIP message solution for sending logic messages to the controller. Considering the CIP connections counter, it seems feasible, but testing with multiple FTLinx servers could present challenges, making it appear as a Studio connection. While I'm not looking forward to it, using audit logs may be the only feasible option.
Upon reviewing the audit logs, it appears that only changes made to the controller are recorded, rather than basic connections from Studio 5000, which is unexpected. I was under the impression that all activities would be logged. Nonetheless, being able to monitor changes and identify the user responsible for the modifications would be beneficial. Is there a method to access the audit log's text using a message instruction? One potential solution could involve writing the log to the SD card and using removable flash memory to retrieve the file's text. While this approach may require a substantial amount of effort, it could be worth exploring in order to access the information needed.
Hey Trevor, you can indeed use the MSG (message) instruction to communicate with the controller via CIP. You need to configure the MSG instruction to read a specific attribute of that controller (like, its status for instance) and then examine the returned status. If the controller responds, then it's online; if it times out or if you get an error, then it might be offline. I hope this helps!
Hey Trevor, you could indeed use a CIP (Common Industrial Protocol) object to get that info. By using a MSG instruction, you can set up a CIP Data Table Read or Write to communicate with your controller at regular intervals. If the status value becomes non-zero, you'll know the controller is offline. The guide at the Rockwell Automation website on setting up MSG instructions should be very helpful for your concern. Fingers crossed!

Answer: 1. How can I check if a controller in ControlLogix is online using logic? - One possible method is to use a CIP object for querying the controller's status. This can help determine the online status through logic.
Answer: - Utilizing CIP objects for querying can be a useful approach. Additionally, exploring different logic-based methods within ControlLogix programming may provide further insights.
Answer: - Querying a controller through CIP objects involves sending specific requests to the controller to retrieve information about its status, including whether it is online or offline. This method can be implemented in the logic programming to determine the online status of the controller.
