■
Overview
The SCALANCE M812-1 and M816-1 are DSL routers for low-
cost and secure connection of Ethernet-based subnets and
programmable controllers to wired telephone or DSL networks
and support ASDL2+ (Asynchronous Digital Subscriber Line).
This allows the devices to have high downlink data rates of up to
25 Mbit/s and uplink data rates of up to 3.5 Mbit/s.
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).
Product versions
SCALANCE M812-1:
•
1 x RJ45 interface with 10/100 Mbit/s for Industrial Ethernet
•
Router functionality can be activated as required (PPPoE pass
through); modem functionality as default value
SCALANCE M816-1:
•
4 x RJ45 interfaces with 10/100 Mbit/s for Industrial Ethernet
•
Configuration data can be saved by means of the C-PLUG
storage medium (not included in the scope of delivery)
■
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 wired telephone or
DSL networks
•
Easy to use with existing infrastructure
•
Improved manageability thanks to mechanical integration due
to the design (module format) with S7-1500 / ET 200MP
•
Wide application area thanks to large bandwidth, high perfor-
mance and speed
•
Worldwide application
■
Application
The SCALANCE M812-1 and M816-1 are suitable for 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 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
Note:
Due to the integral security functions, the SCALANCE M812-1
and M816-1 DSL routers enable a protected connection of
distributed automation cells to a control center via wired
telephone or DSL networks 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.
