Siemens routers enable remote access to automation networks

These new additions are particularly suitable for applications where wireless communication is either restricted or impossible, for example, in water treatment plants or in medical environments.

As asymmetric digital subscriber lines (ADSL) routers, the Scalance M812-1 and M816-1 ensure reliable and low-cost connection of Ethernet-based subnets and programmable controllers to wired DSL networks that support the ASDL2+ (Asynchronous Digital Subscriber Line) protocol. The new routers also offer transmission rates of up to 25Mbit/s from network to end device (downlink) and 3.5Mbit/s from device to network (uplink).

The Scalance M826-2 SHDSL router (single-pair high-speed digital subscriber line) is connected to the Ethernet by means of private two-wire or stranded cables, ensuring fast transmission rates of up to15.3 Mbit/s which can be boosted accordingly in case of installations with four or more wires.

Mark Freeman, Product Manager for Siemens UK & Ireland, comments: "Like all Scalance M products in the portfolio, the new DSL routers are robust and reliable, offering a variety of security functions. For example, the integral firewall and end-to-end encryption, achieved by setting up IPsec tunnels, protect user access and provide secure communication for use across manufacturing environments."
