if i read your post correctly, you are trying to add external node (not specified) in addition to internal node consisting of EK1100 and EL6695.
Thank you for the reply. Yes, the external node is a cRIO ECAT S.
Problem solved: i opend up the sunrise cabinet, and i found that both EK1100 and EL6695 are not powered 😅, so i powered them up using an externel 24VDC power supply and run the wires through a terminal (X55).
