Thanks for this video, this new kind of robot are very interesting for small application where we have to be flexible with the production.And this features of communication.I also try the application simulator on ubuntu, it's very easy to programm it
Thanks for this tutorial. Very helpful. I'm wondering if you made it with an Ethernet/IP device. I'll realy appreciate if you have an example or any sugestion.
Can this be tested with a regular computer ethernet cable connection to a windows pc with some modbus software on windows to send digital/analog values?
I assume that you are talking about having the robot recognize the I/O on an RSLogix PLC? I'm not familiar with Allen Bradley, but I would guess that you could map the I/O on the PLC provided it supports Modbus TCP over Ethernet. You would simply need to know the register addresses for the bits that correspond to the I/O you are interested in, and you would set it up the same as shown in the video.
Jesse Elizabeth Stalman - in this case the UR is considered the Client (Master) and the I/O unit is the Server (Client), though the robot can act as either one.
Ok makes sense, I'm new to Modbus so this may seem like a stupid question. If I have 2 UR robots in a cell and I want them to talk to a Rockwell PLC through a Prosoft Comm Card, would I have to have a card for each Robot or could they share a card through a network switch? If they can share a switch can other devices speaking Ethernet/IP be on that same switch?
The two robots will likely be accessing the same data bits from the PLC, so I wouldn't think that you should need two different cards. You will simply give the robot the address of the PLC (or the card possibly) when you go to setup the I/O. Not an expert on Ethernet/IP, but I know it does cause a fair bit of network traffic. I think you should still be OK sharing a network switch though.
