I've seen many applications that used the dual ports in a daisy-chain configuration. Is the main drawback that all downstream devices go away if one in the middle is powered off? Or is there another reason too?

Are the products all the same size? If so, I would first create an array big enough to have one position for each place a product could be on the conveyor. Array could be bits or integers, depending on how much info you want to track. Use the encoder to advance the array. Write to the right spot in the array at the sensor and read from it at the "store" position. That's my first pass thought.

I replied to your PM.

I've been in the habit of running all of my automation software in virtual machines since about 2011 or so. If that's the only software you need, you could try it on Win11 and it will most likely be just fine even though it's not officially supported. If you ever need to run more software packages in the future, though, I would seriously recommend virtual machines.

There's a tech note (access level: TechConnect): https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/1136965/loc/en_US#__highlight Several things to try are listed there.

Interesting...I'm not sure if I have that problem or not, but my test bench 1769-L33ER (v34.11) is 2.5 hours fast right now. It's been a while since I checked the CPU time, so it may have been drifting for a very long time.

Well, there I go not spending enough time reading the details...

Isn't that for a Profibus slave? OP wants to connect a Modbus RTU Slave to a Profibus Master

No personal endorsement, but I've seen other products from Anybus that seemed solid: https://www.anybus.com/products/gateway-index/anybus-xgateway/detail/anybus-x-gateway-profibus-master-modbus-rtu-slave Do you think that one might work? I checked ProSoft first but they only have Profibus to Modbus TCP, not RTU.

What version of TIA Portal are you using? Do you have WinCC Basic? I don't have that software any more, but I do remember it being version sensitive. But that may have changed with newer versions.

Here's just lad 2. It printed the whole thing when just doing an individual ladder file. MTVAC35_Lad2.pdf

That's crazy. The preview shows all rungs, and I could have sworn I double checked the pdf but it's not there.  

I think you're going to have trouble with that distance. Just as a reference, I pulled up the guidelines for Rockwell drives (because they're handy) and the max distance they support with filtering varies by size and series of drive but maxes out at 365m or so. https://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf   Your distance is almost 6 times longer than that. Definitely reach out to your drive manufacturer for guidance. You may end up having to build an enclosure near the pond for the drive.

Try this. "Microsoft Print to PDF" is pretty awful, it seems. Some pages ended up missing and the file size always seems huge. MTVAC35.pdf

Hmmmm, that is weird. I told it to print the whole thing but it looks like it didn't work right. LAD 2 has 140 rungs. Let me try again with a different print driver.
