Where ’adapter’ is referred to below, the text applies to both
variants.
The PC adapter connects a PC to the MPI/DP interface
(Multipoint Interface) via the serial COM port of an S7/M7/C7
system.
This does not require a PC slot, that is, the adapter is also
suitable for use in non-expandable PCs such as notebooks.

With ’direct connection’, the TS adapter allows you to link
programming devices/PCs with S7/M7/C7 systems. With this
setup, the TS adapter corresponds in functionality to the PC
adapter.
With ’modem connection’, the TS adapter enables you to link
programming devices/PCs with S7/M7/C7 systems over the
telephone network.

The two adapter types differ with respect to the location of the
MPI/DP parameters:
S The MPI/DP parameters for the PC adapter are set in
“Set PG/PC interface”. When opening an online display
for the first time, ther parameters are transferred to the PC
adapter.
S The MPI/DP parameters for the TS adapter are set via a
Teleservice application and stored permanently on the TS
adapter. When opening an online display for the first time,
these parameters are activated.

A maximum of 32 nodes can be interfaced to an MPI/DP
network segment. The total cable length may not exceed 50
meters. Using so-called RS485 repeaters, several network
segments can be combined to form a network comprising a
maximum of 127 nodes.
The data signalling rate in an MPI/DP network is max. 12
Mbit/s.

6.1Safety-related Guidelines
Qualified Personnel
A device/system may only be commissioned or operated by
qualified personnel. Qualified personnel as referred to in
safety guidelines in this document are persons authorized to
energize, de-energize, clear, ground, and tag circuits,
equipment and systems in accordance with established
safety practice. For a detailed description of the
safety-related guidelines, please refer to the Appendix.
Proper Usage
Please observe the following:
Warning
!
The equipment/system or the system
components may only be used for the
applications described in the catalog or the
technical description, and only in combination
with the equipment, components, and devices of
other manufacturers as far as this is
recommended or permitted by Siemens.
The product will function correctly and safely only
it it is transported, stored, set up, and installed as
intended, and operated and maintained with
care.
Cleaning the Device
The device may be cleaned only using a soft cotton cloth and
neutral detergent. Make sure that no liquid penetrates the
housing.

6.2General Remarks
MPI/DP side:
Adapter and S7/M7/C7 system each represent one network
node. In networks comprising two nodes (adapter and
S7/M7/C7 system), the adapter is plugged directly into the
S7/M7/C7 system’s MPI/DP port; in networks consisting of
more than two nodes, the adapter is plugged into a Profibus
connector’s “PG port” (SINEC L2 bus connector); for details,
please refer to catalog IK10.

PC/TS AdapterQuick Reference Guide
As the adapter receives its power supply via the MPI/DP interface, 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). Therefore 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:
S See 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”).

Warning
!
The RS232 cable listed under Point 3
(Accessories) ensures that EMC requirements
are met.
This cannot be guaranteed if you use a different
cable and you do so at your own risk.
S See Figure 1-2 “TS Adapter in the System” for details of
modem connection. A modem is connected to the RS232
interface of the TS adapter using the enclosed RS232
cable. In the modem description, this cable is used for
connecting the modem to a PC. If this modem cable does
not have a 9-pin SUB-D socket connector on the TS
adapter side, the relevant adapter must be used
(Figure 1-5).

6.5Function and Operation of the Switch
The switch is used for setting the transmission rate
(19.2 kbps or 38.4 kbps) on the RS232 side of the adapter
variant in direct connection. It has no function with modem
connection.
The transmission rate set with the switch must agree with the
rate parameterized for the PC in “Set PG/PC interface”.
Note
A Transmission speed of 38,4 kbit/s is only possible using
STEP 7 Version 3.1 or higher.

The switch is operated only infrequently and is recessed so
that it cannot be operated inadvertently. See Figure 1-11 for
the location of the switch. Both switch positions are labeled
on the underside of the unit.
To operate the switch, please use a ball-point pen
(“retractable ball-point”) up to a diameter of 1.7 mm or a blunt
instrument of the same size. Insert the extended point
between the operating lever and the housing cutout on the
side with the operating lever, and slide the operating lever
into the opposite position (see Figure 1-11).
Warning

Pointed objects (for example, needles) or
breakable objects (for example, pencils) must not
be used for operating the switch.
