• Router REX 300 The REX 300 industrial router provides you with maximum flexibility and greatest possible security. With the router, you can remotely establish simple and secure communication with your plants. Due to its S7-300* design, the REX 300 can easily be integrated into an S7-300* system and, with the included PG/PC interface driver, it can be used within all common Simatic* Engineering Tools. The REX 300 is easy to configure via its web user interface. Irrespective of the way the connection with the internet is established (analog, ISDN, EDGE/GPRS/GSM or DSL), the integrated, application-oriented configuration wizard makes configuration of the VPN, internet, and network connection easier. It permits ready-to-use configuration within a matter of minutes.

  • SSW7/TS300 The SSW7-TS can be used to teleservice your system via a modem connection. For this, you can connect a commercially available external modem (analog, ISDN, GSM) to the RS232-interface of the SSW7-TS. For local use, you simply connect the RS232 interface of the SSW7-TS to your PC. The SSW7-TS automatically detects the baud rate (9.6–115.2 kBaud) used by the PC. At the system end, you can connect the SSW7-TS to an MPI network with 187.5 or 19.2 kbps.The PC must be installed with the teleservice module for the programming software (e.g. TeleService for Simatic* STEP* 7) so that the SSW7-TS can be parameterized if necessary, and the modem connection maintained. Without modems or the teleservice module the SSW7-TS can be operated at the machine as a SSW7. With the TS 300, teleservice of a system can be performed via the MPI bus. The TS 300 has a single-width S7-300* housing for mounting on the sectional rail. A 56k modem is integrated into the housing of the TS 300 that is prepared for use worldwide. A flash update is no longer necessary. TAE and RJ11 cables are included in the scope of supply. As alternatives, versions with ISDN or GSM modem are also available. The TS 300 can establish an MPI link with the CPU via the backplane bus. The power supply is also drawn from the backplane bus. Therefore, for installation of a teleservice solution, only the phone line is required. The TS 300 does not need to be configured in the hardware configuration of the PLC and can therefore be retrofitted at any time.

  • Modem The MDM 300 of Systeme Helmholz GmbH is a universal modem that can be installed in a single-wide S7-300* housing for the sectional rail. A 56 k modem is integrated into the housing of the MDM 300 that is prepared for use worldwide. Alternatively versions with ISDN or GSM functionality are also available. The SSW7-TS with an integrated modem is a low-cost alternative to teleservice a programmable controller via the MPI bus. Depending on the version, an analog, ISDN, or GSM modem is integrated in the housing of the SSW7-TS. The analog modem can be configured for worldwide use. The ISDN variant supports the DSS1 protocol that is used in many countries. All connecting cables required for operation are included. The SSW7-TS with a GSM modem (quadband) is the right choice for mobile use or if a telephone connection is not available. The SSW7-TS PRO can be used for teleservicing a S7 system via a modem connection and supports to the connection of the system to an MPI or PROFIBUS network with up to 12 Mbps. Depending on the version, an analog, ISDN, or GSM modem is integrated in the housing of the SSW7-TS PRO. The MPI/PROFIBUS connecting cable of the SSW7-TS PRO is not a spur line because of the repeater integrated into the connector. It allows the adapter to be connected at any point along the bus even at 12 Mbps. New: As a new feature, the SSW7-TS PRO now also supports transmission of any SMS messages. SMS transmission is triggered by calling the SMS_SEND function block from the programmable controller. Depending on the SMS service provider used, it is also possible to send messages to an e-mail address or fax machine.
