Hello everyone, I am looking for cost-effective solutions to integrate a single AI (temperature) signal from a remote location that is 2 miles away into a ControlLogix PLC. Would a remote terminal unit with a radio be a viable option? Alternatively, should I consider using an RIO module within the local ControlLogix system? Let me know if you have any suggestions on how to achieve this efficiently.
One user on the scada.plc forum posted a query asking for help on implementing a single AI (analog input) using a PLC. Can anyone clarify what is meant by "single AI" in this context?
Is there internet access or cell service available at the remote location?
When referring to "Local Contrologix," are you asking if it is local to the analog signal's source or local to your current location? If there is a Contrologix PLC where the analog signal originates, connect it to that PLC and establish Produced/Used tags for your own PLC to access the data. Alternatively, you can transmit the value using messaging capabilities.
WhinnieThePooh inquired about the concept of a "single AI." In this context, AI stands for analog input, such as the temperature measurement at a distant site that needs to be incorporated into a ControlLogix system locally. Assuming a 4-20ma signal can be obtained from the remote temperature device, the task involves reading this single AI into the ControlLogix PLC, likely through a radio transmission. What would be the optimal solution for ensuring seamless communication on both ends of this remote connection?
There is currently no CLX present at the remote site. Technicians can currently view temperature readings on a local display. I am seeking a more efficient solution to eliminate the need for technicians to travel to the remote location daily to retrieve this data.
Absolutely, a remote terminal unit with a radio could indeed be a viable option - it's useful for long range applications. Though, remember to consider environmental factors that could affect the radio signal. As for the RIO module in your local ControlLogix system, it could work, but it typically depends on the network infrastructure you have in place. Also, there's another route you might want to consider: combining the simplicity of wireless temperature sensors with the power of IoT platforms. It could be cost effective, easy to deploy, and gives data in real time. You might need to see what suits your set-up best.
Both solutions could work depending on your specific requirements and constraints. A remote terminal unit (RTU) with a radio would definitely help collect the temperature data and transmit it wirelessly over the distance. However, keep in mind any potential interference or obstruction issues. On the other hand, using a RIO module within your local ControlLogix system offers a more reliable, wired solution, but it might be more costly and complex to set up, especially considering the distance. It's important to consider these variables and balance efficiency and cost.
