Features:
- An integrated analog modem connects the TeleService adapter to an analog telephone network.
- The MPI/DP interface links remote service traffic to a SIMATIC S7 or C7 automation bus.
- RS232 supports an external-modem path while USB is reserved for local parameterization.
Siemens 6ES7972-0CB35-0XA0 converts a remote analog-line session into communication with the connected MPI/DP station.
The RS232 and USB connectors on 6ES7972-0CB35-0XA0 serve external-modem and local-setup tasks rather than the same traffic path.
Power for 6ES7972-0CB35-0XA0 comes from the MPI connector or a valid external 24 V DC feed.
The Siemens 6ES7972-0CB35-0XA0 SIMATIC S7 TS Adapter II Analog TeleService Adapter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Automation Bus Connection
- Bus role: The RS485 interface carries service communication to the connected MPI or PROFIBUS DP network.
- Bus rate: The adapter follows the configured network rate up to the documented maximum.
- Station access: Remote communication reaches only the S7 or C7 stations permitted by the network and TeleService configuration.
- Startup check: Bus address, connector, cable, termination, and network parameters must agree with the installed segment.
Telephone and External-Modem Roles
- Analog line: The RJ12 connection links the integrated modem to the analog telephone network.
- Integrated modem: The modem converts telephone-line signaling into the adapter communication session.
- RS232 option: The serial interface connects a documented external modem when that path is configured.
- Line diagnosis: Dialing, country settings, line quality, modem response, and remote number must be checked separately from MPI/DP.
Local Parameterization Interface
- USB role: USB 1.1 provides a local engineering path for adapter parameters.
- Data rate: The local USB connection operates at the documented full-speed rate.
- Parameter set: Bus, modem, access, and TeleService settings are written to the adapter before remote use.
- Boundary: USB setup does not replace the telephone, RS232, or MPI/DP operating connections.
Supply Selection and Commissioning
- MPI supply: The adapter can receive operating power from the connected MPI interface.
- External supply: A separate 24 V DC source is available when the bus cannot provide the required power.
- Startup current: The supply path must tolerate the documented inrush without dropping below the operating range.
- Commissioning order: Confirm supply, local parameters, bus access, modem response, and remote login before enabling service use.
