High data transfer rate thanks to HSDPA
Integrated security functions with firewall
Use as VPN end point (IPsec)

Область применения

Can be used in industrial and semi-industrial applications due to its design and electrical properties
Remote programming and maintenance worldwide, e.g. with STEP 7 via the high-speed UMTS interface
Linking of mobile stations, with central monitoring and control
Energy-saving concepts in distributed systems, e.g. through status-dependent speed control of pumps in remote stations
Control and monitoring of
- Sewage treatment plants, water treatment
- Oil and gas supplies
- District heating networks
- Power distribution
- Pumping stations
- Transportation systems
- Buildings
- Wind energy and photovoltaic plants
Connection of telecontrol substations (e.g. SINAUT ST7) to control center via UMTS
Video transmission e.g. from moving vehicles such as buses and trains
Can be used worldwide due to:
- UMTS: Penta-band technology
- GSM: Quad-band technology

Note:

Country-specific approvals must be observed.

Due to the integral security functions, the SCALANCE M875 UMTS router enables protected connection of distributed automation cells to a control center via the mobile wireless network, and it can be used within the scope of the Siemens Remote Service. This comprehensive service allows companies to task Siemens with the monitoring, control and maintenance of distant plants and machines via remote access.

Configuration

User-friendly configuration of all network and firewall parameters of the router using the web browser

Security

Router for data transmission via public networks with NAT functionality (NAT Traversal, NAPT, 1:1-NAT)
Suitable VPN termination of the control center via SCALANCE S
Firewall for protection against unauthorized access; the dynamic packet filter checks data packets based on the source and target address (stateful inspection) and blocks undesirable data traffic (anti-spoofing)

Diagnostics / maintenance

Status of connection buildup and of an existing connection via front LED display and web browser

Preconditions for using the SCALANCE M875 UMTS router

SIM card from a UMTS network operator with HSDPA support, or alternatively a SIM card from a GSM network operator with eGPRS or GPRS support

Интеграция

Application example: SCALANCE M875 for remote maintenance with VPN tunnel

Classical applications such as remote programming, parameterization and diagnosis, but also monitoring of machines and plants installed worldwide can be performed securely via a VPN from a service center that is connected over the Internet. Access to any IP-based devices, especially IP-based programmable controllers, which are downstream of the SCALANCE M875 in the local network.

Multimedia applications like video streaming can be implemented thanks to the increased bandwidth in the uplink.

Application example, broadband data transmission in vehicles with SCALANCE M875

The UMTS router SCALANCE M875, with its high down-link and uplink capacity, supports numerous data services with large bandwidth requirements via mobile wireless to and from vehicles. To increase the connection quality during motion, SCALANCE M875 is equipped with antenna diversity. Sensitive data can be transmitted in a secure VPN tunnel if required.

Video transmission in real time from the passenger cell is used to increase passenger safety (video surveillance). The video data from all vehicles is sent to a control center for monitoring and further processing.

In addition, applications such as data interfacing for ticket machines, infotainment services and internet on board, or proactive monitoring of vehicle engineering (telemetry) are also possible.

Broadband video data transmission over UMTS, protected via VPN, to increase passenger safety

Особенности

Low investment and operating costs for operator control and monitoring of wirelessly connected telecontrol substations
Reduced travel costs and telephone charges thanks to remote programming and remote diagnosis via UMTS
High level of security thanks to an integrated firewall and VPN with IPsec
Utilization of existing UMTS/GSM infrastructure of the mobile radio providers
Worldwide application
