I started a thread on this a while back, but I got the basics working and now onto troubleshooting, hence the new thread. I'm copying a text string to V2000 and then signaling my CoPro (via send/busy bit C63) to grab that data and pass it on to a STP-DRV-4850. Once the string is sent, the CoPro ensures that the string is accepted by the step drive, then clears the send/busy bit C63 so my DL06 can send the next string, etc. It sends the first string just fine, but it does not send any subsequent strings beyond that. I attached a picture of the ladder where it hangs up, and a copy of my CoPro program for reference. I 've done similar sequencing on a Click in the past to make sure that I do not overload the step drive's input buffer, and I believe this is setup correctly in my DL06. For reference, this sequence resides in a subroutine, but I don't see why that would pose any problems, because my ladder logic calls the subroutine and gets to the spot where it hangs just fine. As always, any help and/or insight would be much appreciated! Does anyone see something that I don't? Would this be something better suited to its own Stage instead of a subroutine?

Figured this one out. I did not latch the subroutine in the main body, so it ran through the subroutine only once before all the commands could be executed.
I'm still not getting the step drive to run, but I'll try some things before posting details of that one. Thanks for looking, at least!
