text: <s>[INST] PowerFlex 700 20-COMM_E Problem I have hooked up two PowerFlex 700 drives to a ControlLogix processor via a 1756-ENBT card. The drives are the only things that are on the network. The first drive connects but then faults out on a F75 (Port 5 Adapter) fault and the second drive will not connect because of a Code 16 [/INST] Both errors could happen due to a wrong connection size setting in RSLogix5000 IO configuration. See Aid 53820 and Aid 45272 (this is done for SMC-Flex, but applies also to a PF700)Follow carefully the configuration steps indicated in the 20-COMM-E User Manual. Hope this helps, - fuzzy logic \\n </s>
