How to Troubleshoot Rockwell PLC AOI Output Display Issues

Question:

Having trouble displaying outputs on AB/Rockwell PLCs like the example image? The manufacturer's output shows multiple blocks, but my AOIs are always a single block. Unsure of the configuration setting I'm overlooking. I've been struggling with this issue for months. Any suggestions or solutions would be greatly appreciated. Thank you.

To adjust the visibility of the AOI, simply right-click on it and choose "Properties." Next, navigate to the "Parameters" tab and ensure the "Visible" column is selected. Then, proceed to redownload the AOI to apply the changes.

In order to resolve the issue of a big rectangular block appearing, try right-clicking on the AOI, selecting properties, navigating to the parameters tab, and ensuring that the "visible" column is checked. If the issue persists, consider re-downloading the required components.

Deselect "req" and select "visual" for status tags.

Yes, that solution was effective. Thank you.

It sounds like you might need to configure your AOIs to support structured tags. In your AOI definition, try defining your output or input tags as a UDT (User-Defined Type) rather than individual bits or words. This allows you to group the tags in a structure which should then show up as multiple blocks on your PLC. Also, be sure to check if there are any specific Rockwell software updates that you're missing out on, sometimes they help with finer optimizations. Hope that helps!

It sounds like you might be dealing with a graphical formatting issue in the software. You can try extending the AOI block in the ladder diagram to facilitate multiple lines. This would mimic the multiple block layout present in the manufacturer's output. If this doesn't work, it could be a software compatibility issue, so updating your Rockwell software might help. Also, remember that some AOI designs are inherently single block and require slight modifications to have multiple outputs. Hope this helps, and hang in there - PLC troubleshooting can be quite a challenge but super rewarding once resolved!
