This also enables Safety Integrated-supporting functions for linkaxes, such as velocity/speed monitoring-dependent setpoint limiting and higher-order stopfunctions (STOP D/E).NoteThe Safety Integrated functions "Safe software limit switch" (SE) and "Safe software cam, safecam track" (SN) are not (yet) supported.Link moduleThe link communication requires optional link modules. A link module is an optional PROFINETmodule for isochronous real-time communication (IRT) via Ethernet. The link module occupiesthe option slot of the NCU.B3: Distributed systems - 840D sl only3.1 Brief descriptionExtended Functions78 Function Manual, 10/2015, 6FC5397-1BP40-5BA3
