Hopefully quick question here. I'm working on my first multiple robot application and i want to build in some cross controller communication via Ethernet to keep their movements in sync with each other. I haven't found a good way to do that. Anyone have a good solution for this? It doesn't need to be very robust, I was planning on just sending move completions back and forth. Both controllers are also linked to a PLC that is controlling them both. I could use the PLC to snyc them, but I would rather have it bypass the plc as a secondary system.
Update: I found the IO Cell Linker tool and have successfully 'linked' the digital out and the digital input. However when the program runs, the input status is a "?" as if it isn't reading the value. I tried doing a dioGet and just using the digital output ex: wait(do_link==true) but the "?" never goes away.... I tried a full power down to see if the IO needed to update but haven't been able to figure out this issue.
Thanks in advance!
