More Information

Overview Manuals Remote Access Path Interface Roles Adapter Setup Status Diagnosis

Features:

  • An integrated analog modem terminates the remote telephone connection.
  • The RJ45 interface carries the resulting service session onto Industrial Ethernet.
  • A separate RS232C port supports the documented external-modem path.
Remote TeleService traffic is converted from the telephone side into routed Ethernet communication.

Link and traffic LEDs expose the physical state of the local network connection.

Adapter administration keeps modem, network and access parameters in one device.

The Siemens 6ES7972-0EM00-0XA0 SIMATIC TS Adapter IE Analog Modem may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Following a service session from the caller to the controller

  • Telephone entry: The integrated modem accepts the configured analog-network call.
  • Session control: Adapter credentials and modem parameters govern whether the connection proceeds.
  • Ethernet routing: Accepted IP traffic crosses the RJ45 link toward the automation network.
  • Controller reach: The engineering application addresses the intended S7 or C7 component through that route.

Keeping three communication connectors distinct

  • RJ11 port: The analog telephone line terminates at the internal modem.
  • RJ45 port: Industrial Ethernet connects the adapter to the programming device, controller, or switch.
  • RS232C port: A supported external modem uses the separate serial path.
  • Connector check: Each cable belongs to one interface and cannot substitute for another.

Coordinating network, modem and access parameters

  • Network identity: The IP settings place the adapter on the intended Ethernet segment.
  • Modem profile: Dialing and country parameters define the telephone-side behavior.
  • User access: Configured credentials restrict administration and remote sessions.
  • Route test: A successful test confirms both the remote call and the local Ethernet destination.

Separating supply, link and traffic faults

  • Power state: The 24 V input must be present before either communication side can operate.
  • LINK indication: The green LED reports whether the Ethernet physical link is established.
  • RX/TX activity: The yellow indicator shows frames crossing the local network port.
  • Path isolation: Telephone, serial and Ethernet checks are performed independently before changing configuration.
Description
Siemens 6ES7972-0EM00-0XA0 is the SIMATIC TS Adapter IE analog-modem variant for TeleService access to S7 and C7 automation components over Industrial Ethernet. A remote call reaches the integrated modem, and the adapter routes the authenticated session toward the connected Ethernet network.

On the plant side, the RJ45 port of 6ES7972-0EM00-0XA0 connects directly to a programming device, an automation component, or a network switch. Link and RX/TX indicators separate a missing physical Ethernet connection from a session or modem problem.

The analog RJ11 path of 6ES7972-0EM00-0XA0 serves the public telephone connection, while its RS232C interface is reserved for the documented external-modem option. These interfaces provide different communication paths and are configured separately in the adapter administration pages.

Power for 6ES7972-0EM00-0XA0 enters through the isolated 24 V DC supply connector rather than the Ethernet link. The network address, modem parameters, user credentials, and routing settings must all agree before TeleService traffic can pass between the remote caller and the automation network.

Technical notes
Remote access through Siemens 6ES7972-0EM00-0XA0 depends on the configured Ethernet address, analog line, 24 V supply, and TeleService connection settings.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can Siemens 6ES7972-0EM00-0XA0 answer a call but not reach the controller?
Check the Siemens 6ES7972-0EM00-0XA0 Ethernet link, IP settings, routed destination and TeleService access parameters after the modem connects.
Which cable belongs in the analog port of 6ES7972-0EM00-0XA0?
The 6ES7972-0EM00-0XA0 analog telephone connection uses its RJ11 modem port; the RJ45 socket is reserved for Ethernet.
How should the RS232C interface on 6ES7972-0EM00-0XA0 be used?
Use the 6ES7972-0EM00-0XA0 RS232C interface only for the supported external-modem path and keep its parameters separate from the internal analog modem.
What should be recorded before replacing Siemens 6ES7972-0EM00-0XA0?
Archive the Siemens 6ES7972-0EM00-0XA0 IP configuration, modem settings, user access data, routing details, and cable assignments.
Does an active LINK LED prove that 6ES7972-0EM00-0XA0 remote access is complete?
No. The 6ES7972-0EM00-0XA0 LINK LED confirms only the local Ethernet connection; modem, authentication, and routing checks remain necessary.
