■
Overview
The SCALANCE M874-3 is a mobile wireless router for cost-
effectively and securely connecting Ethernet-based subnets
and programmable controllers via the 3rd generation mobile
wireless network (UMTS) and it supports HSPA+ (High Speed
Packet Access). Thus, it allows high transfer rates of up to
14.4 Mbit/s in the downlink and up to 5.76 Mbit/s in the uplink
(depending on the infrastructure of the mobile wireless
provider).
The SCALANCE M874-2 is a mobile wireless router for cost-
effectively and securely connecting Ethernet-based subnets
and programmable controllers via the 2nd generation mobile
wireless network (GSM) and it supports GPRS (General Packet
Radio Service) and EDGE (Enhanced Data Rates for GSM
Evolution).
The security of access and communication is ensured by the
security functions of the integrated firewall and by VPN tunnels
(end-to-end connection encryption through IPsec tunneling).

Benefits
•
High security standards by means of a firewall (stateful packet
inspection) and VPN connections (IP-Sec) as an integral
component of the Industrial Security concept
•
Low investment and operating costs for operator control and
monitoring of remotely connected substations
•
Reduction in traveling costs and personnel costs due to
remote programming and diagnostics via mobile wireless
networks
•
Improved manageability thanks to mechanical integration due
to the design (module format) with S7-1500 / ET200MP
•
Wide application area thanks to large bandwidth, high perfor-
mance and speed
•
Application-dependent use of mobile wireless services
(2nd and 3rd generation)
•
Worldwide application
■
Application
The SCALANCE M874 can be used in industrial and semi-
industrial applications:
•
Worldwide remote programming and servicing, e.g. using
STEP 7 via mobile wireless
•
Worldwide flexible plant access for servicing and diagnostics
purposes
•
Connection of static and mobile stations for controlling and
monitoring such things as:
- Water/wastewater treatment plants
- Oil and gas supplies
- District heating networks
- Power distribution
- Pumping stations
- Transportation systems
•
Worldwide condition monitoring, e.g. for
- Wind energy and photovoltaic plants
•
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 M874
mobile wireless 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.
