8PC/TS Adapter

A5E00078070-02

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”).
