Thank you for the reply Michael_A. Unfortunately, I only have one ctrlX Core which I have just upgraded to V1.20 but I am pretty sure that this worked, as is, prior to the upgrade. The dual axis drive appears on the EtherCAT network as one device. When I setup a profile and select that device, I see the cyclic data for both axis: So for 'Profile 1' I would map to: AT_1 Drive_Status_Word & Position_feedback_value_1 MDT_1 Master_control_word & Position_Command_value And for 'Profile 2' I would map to the corresponding AT_2 & MDT2 cyclic data variables This is my recollection of how I set the system up on V1.12. Thanks
