PC/TS Adapter Quick Reference Guide

As the adapter receives its power supply via the MPI/DP in- terface, only those interfaces can be used which provide

24 V DC and 5 V DC with the voltages and currents specified in the table in the ”Technical Specifications” (Chapter 7). The- refore a connection at the free end of a PROFIBUS cable is not possible.

The adapter provides electrical isolation between its MPI/DP interface and RS232 interface within a safety extra-low voltage (SELV) circuit, thus allowing direct operation even on ungrounded S7/M7/C7 systems.

RS232 side:

SSee Figures 1-1/1-2 “PC/TS Adapter in the System” for direct connection details. An RS232 cable is required to connect a PC/programming device to the adapter’s RS232 interface (COM2-PC-compatible). This cable must be ordered separately (see 3. “Accessories”).
