The bus connector Profibus Compact 2 is tailored for the new control SIEMENS SINUMERIK NCU 7×0.3 PN control. The compact bus connector provides more space for the cabling and thereby meets the special dimensional requirements of the new NCU 7×0.3 PN. It is used to connect the Profibus cables with the Profibus DP interfaces (X126 and X136) of the control unit and thereby establishes the connections to other participants.
