Drives and distributed I/O are linked to SIMATIC TDC using PROFIBUS DP interface modules with master and / or slave function.

Multiple SIMATIC stations, as well as external systems and host computers, can be networked using a TCP/IP interface modules for up to 100 Mbit/s. Visualization components such as WinCC can also be linked via this interface module.

All the visualization components of SIMATIC HMI, such as WinCC or OP/TD panels are also linked via the MPI (multi point interface).
