Westermo Data Communications has released two industrial routers designed to be compatible with the current and future requirements of remote telemetry and industrial control systems applications. They can also be used for remote sites access, allowing the user to browse WEB pages, monitor / edit PLCs or access any device connected to the LAN. They will allow devices on the LAN side to send emails or connect to FTP servers for transferring files.
The MR-200 router is a GPRS router with an integral Ethernet port and a 25 pin RS-232 serial interface for local connectivity. The Ethernet interface supports Multicasting (IGMP), VLAN, SNMP, SNTP, FTP, SNMP as well as all the standard TCP, UDP and DHCP protocols. The inbuilt RS-232 port can be used to connect legacy serial based equipment such as PLCs, RTUs or Intelligent Electronic Devices. Alternatively the internal serial port can be used as a backup connection to the remote site when used in conjunction with a suitable Westermo Modem.
The DR-200 router uses ADSL broadband technologies to give high speed access to remote sites over an existing analogue telephone connection, at speeds of up to 2 Mbit/s. The unit has an integral four port Ethernet switch and a 25 pin RS-232 serial interface for local connectivity.
Both routers have an integrated stateful inspection firewall and can support 5 IPSEC VPN (Virtual Private Network) terminations which can be secured using optional 3DES, AES, SSL, SSH encryption, and MD5, SHA1 key exchange protocols. These features ensure that the remote sites can use the latest security technology to resist denial of service attacks and hacking. The VPN’s can be used as a way of increasing security and to create secure tunnels, running between sites. The VPNs can be used to interconnect the sites effectively replacing the requirement for dedicated leased lines. The VPN tunnels for both models can be terminated using a either a DR-200 or MR-200. An optional license for 50 VPN terminations is also available.
Both routers support VRRP (Virtual Redundant Router Protocol) allowing multiple physical routers to share a single gateway address and provide multiple backup WAN paths. For complex network applications they support OSPF and RIP2.
The units are supplied with a complete mounting kit for DIN rail, wall or shelf mounting. The wide temperature range (-20 degreesC to +55 degreesC) and 24 VDC supply ensure that they can be used in industrial applications without the need to modification or consideration of the environmental conditions.
