TeleService is stand-alone software and does not require the installation of other software products such as STEP 7.

When using the TIA Portal, the TeleService software is not required because the functions are already a component part of the TIA Portal.

The following functions are available for remote maintenance with TeleService:

• Support for the TS Adapter II, TS Adapter IE and TS Adapter IE Basic
• Parameterization of the modem:
  On the PG/PC side, parameterization using Windows tools is supported. On the line side, the TS Adapter (with default settings) performs parameterization
• Electronic telephone book:
  To support the administration of plants (e.g. telephone number, location)
• Multi-level access protection:
  Prevents unauthorized connection build-up to a plant by means of a password and/or callback telephone number (callback function)
• Callback function:
  The plant calls the service center back automatically following a TeleService call
• Routing of the PG functionality:
  Routing over TeleService is supported in the same manner as for a local connection. S7/M7 CPUs and CP modules with routing capability are required for this purpose
• Import/export of the TS Adapter parameters:
  The parameters can be saved in a file (*.tap) on the PG/PC and reloaded
• Authorization via the Automation License Manager
• Runs under Windows XP Professional, Windows Vista and Windows 7

TS Adapter II; TS Adapter IE and TS Adapter IE Basic provide additional functions

TS Adapter II:

• Establishing a connection from/to remote plants, e.g. for calling up process data from an automation system (PG-to-AS remote coupling)
• Exchange of data between plants (AS-to-AS remote link)
• Exchange of process data between two SIMATIC automation systems
• Sending a text message
• Sending a text message from a SIMATIC automation system via a GSM wireless modem

TS Adapter IE:

• Remote control of HMI devices:
  The TS Adapter IE in combination with a browser installed on the PG/PC (e.g. Internet Explorer) and the Sm@rtViewer supports access over the telephone network to a SIMATIC HMI device with an installed Runtime option of WinCC flexible /Sm@rtService or /Sm@rtAccess. The HMI device or machine/plant can then be remotely controlled from the PG/PC.
• Sending e-mails:
  The function block AS_MAIL (included in the scope of supply of the adapter or TeleService V6.1) can be used to send e-mails directly from a SIMATIC CPU over the TS Adapter IE. The TS Adapter IE builds up an outgoing modem connection to a dial-up server for this purpose, e.g. to an Internet service provider, and sends the e-mails via an e-mail server that can be accessed there. If the provider offers the service for converting e-mails to text messages, text messages can also be sent in this manner.
• Standard routing:
  The TS Adapter IE allows a modem link to be established to an Internet service provider for accessing data on the Internet over this link. While the link is established, telephone dial-up and therefore remote maintenance and remote control is not possible.

TS Adapter IE Basic (in conjunction with a TS module)

• Remote maintenance over the telephone network:
  The TS Adapter IE Basic enables an application running on the PG/PC, such as STEP 7, to access Industrial Ethernet-connected S7 and C7 automation components over the phone network. For this, the TS Adapter IE Basic requires the following:
  
  • A connection to the automation components via Industrial Ethernet, and
  • A modem connection to the PG/PC
• Sending e-mails:
  With the AS_MAIL function block, you can send e-mails from a SIMATIC CPU via the TS Adapter IE Basic. To do this, the TS Adapter IE Basic establishes an outgoing modem connection to a dial-up server, such as an Internet Service Provider (ISP), and sends the e-mails via a mail server accessible there.

To establish a remote connection through the telephone network you will alternatively need:

• TIA Portal V11.0 (contains all the necessary TeleService functions)
• TeleService V6.1 or
• Windows dial-up network

TS Adapter IE Advanced

Functionality:

• Remote maintenance via a VPN connection
• Parameterization via an integrated web interface
• Enabling and disabling of connections, time-triggered if required
• User management with freely-definable password rules
• Logging of security events, exportable
• Own hardware clock, battery back-up, NTP client 
• Configurable package filter
• Port forwarding routing
• NAT, SNMP
• Sending e-mails (via FBs on a SIMATIC CPU)
• Export and import of parameters
• Firmware update

Security:
The TS Adapter IE Advanced provides a high level of security, supported by hardware. System access is only possible via an encrypted VPN connection. Authentification is ensured by certificates.
The user management function enables user accounts with differing access rights to be set up. The firewall can be configured to filter data streams so they exactly fit customer requirements.

Advantages/customer benefits:

• High security standard due to VPN, certificates, hardware-generated random numbers and adherence to strict Siemens security guidelines
• Made-to-measure solutions for remote maintenance in the automation environment
• Transparent routing via web proxies ensures use directly from the company LAN (service side) to the system, with no release or configuration by IT administrators
• Only the TIA Portal is required to build up the VPN connection (VPN client)
  • SSTP (Windows 7 service) behaves like HTTPS access from the browser and is thus transparent in the infrastructure
  • Direct online connection from the TIA Portal at the press of a button (telephone book function: management of multiple teleservice adapters possible)
• Can be used as router or following a default router
• Integrated DCP proxy (support for life-list function as local, and use of topology editor via remote access)

Sending e-mails
The TS Adapter IE Advanced (gateway function) can be used to send e-mails from a SIMATIC-CPU in the system network (LAN) to a communication partner in the public grid (WAN).
The following blocks are available depending on the CPU used:

• TMAIL_C for S7-1500
• TM_MAIL for S7-1200 (for firmware versions V2.x and V3.x of a CPU from the S7-1200 series)
• AS_MAIL for S7-300/400
