SINUMERIK 840D Installation and Start-Up Guide (IAD) – 04.00 Edition
This cable is used for connecting a standard machine consisting of MMC,
MCP and NCK via OPI/MPI.
It must not be used for setting up an m:n installation.
Components must not be connected using internal bus terminators (e.g.
HHU, HPU), because the cable is already fitted with bus terminators.
