The programming port is located on the CPU Module PU11A (EX10-MPU11A), not on the EX10-MCL11 module.
Yes, thank you for clarifying that.
I apologize for any confusion. I thought my question was clear within the context of my previous post. Now that I've read it again, I see that didn't convey my intent. Let me clarify.
My reference to the connections on page 4 of the EXPDD manual 520 applies to the computer link that is built into an enhanced CPU (PU12A). It appears that the computer link is passive not active. Since they are both on the same CPU and you can program from either, I was asking if they both used the same type of current loop. When I stated "what is the programming port", my intent was to ask if the programming port is passive too. It should have read, What is the programming port, active or passive?
I hope this clears things up a bit. Once again I apologize for the confusion.
