Compact Logix 1769-SM2 communicating with 4 Powerflex 40 drives - HELP

[phuz 2]

I have 4 drives setup with this SM2 card and having a bear of a time. First off, the wiring in the SM2 manual is backwards. It shows left wire of SM2 port connected to right wire of drive COMM port, however this is not true. It is opposite. I have verified this in single-drive mode where everything works. As soon as I go back in to multi-drive mode (5X mode on the card), and plug the rest of the drives in, it FAULTS, and the drives show F081 (COMM LOSS FAULT). I have the drives setup for 19.2k baud rate, all the addresses are 100-103 respectively, and setup in the card configuration the same. I am at a loss, and so is Rockwell. Edited 12 Mar 2010 by phuz
