Routers for wired remote access to automation networks & components!

Siemens has extended its industrial remote communication portfolio with three new industrial routers from the Scalance M series of products. The Scalance M812-1 and Scalance M816-1 enable users to access automation networks and components remotely from anywhere in the world over the public digital subscriber lines (DSL) of different providers.

The third new router – the Scalance M826-2 – is designed for communication over private (leased) lines. The new routers are particularly suitable for applications in which wireless communication is either restricted or impossible, for example in the field of water treatment plants or medical technology.

As ADSL routers, the Scalance M812-1 and M816-1 ensure the reliable, low-cost connection of Ethernet-based subnets and programmable controllers to wired DSL networks that support the ASDL2+ (Asynchronous Digital Subscriber Line) protocol. Transmission rates of up to 25 Mbit/s from network to end device (downlink) and 3.5 Mbit/s from device to network (uplink) can be achieved with the new Siemens routers. 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. For two-wire cables the router ensures fast transmission rates of up to15.3 Mbit/s, which can be boosted accordingly in case of installations with four or more wires.

Like all Scalance M products in the portfolio, the new DSL routers are robust and reliable in operation. A variety of security functions, such as an integral firewall and end-to-end encryption by setting up IPsec tunnels, protect user access and provide secure communication.
