IP Routers Fast, Secure Access
Modern factories are comprised of complex equipment and subsystems that communicate via the Internet Protocol (IP) – the backbone of the Internet. The integration of new machines or subsystems can be compromised if they have a fixed range of IP addresses that conflict with other existing plant addresses or the overall addressing policy already in place. Contemporary Controls' CTRLink Skorpion IP routers address this issue – each machine or subsystem (which consists of multiple IP devices) connects to the LAN side of the router while keeping their same IP settings for the devices and the application, thus lowering installation costs and eliminating troubleshooting. The IP address for the WAN port on the IP router is the only setting that requires modification to join the factory network, allowing rapid integration and multiple machines to reuse the same configuration on the LAN side.
Simplify Machine IP Integration
Maintain your factory-set IP addresses when integrating with the customer's IP network by using the Skorpion IP Routers. Reduce installation time, eliminate IP conflicts, and easily comply with your customer's IP requirements.
The EIPR links two 10/100 Mbps Internet Protocol (IPv4) networks — one network is the LAN; the other is the WAN — and passes appropriate traffic while blocking all other traffic. One network is the local-area-network (LAN); the other is the wide-area-network (WAN). The built-in stateful firewall passes communication initiated on the LAN-side while blocking WAN-side initiated communication. With Port Address Translation (PAT), LAN-side clients can access the Internet. Network Address Translation (NAT) allows a one-to-one translation between LAN-side and WAN-side devices. With Port Forwarding, LAN-side devices can be accessed from the Internet. The EIPR incorporates a four-port Ethernet switch for multiple LAN-side connections. An external Ethernet-based modem — cable or DSL — can be used to connect to the Internet. DSL modems connect via the PPPoE protocol. A USB port on the EIPR models allows expansion to wireless networks.
With its real-time clock and OpenVPN® firmware, the EIPR-V can support a virtual private network (VPN) and provide OpenVPN client communication at the job site. It can be used with Contemporary Controls' cloud-based RemoteVPN service to provide secure, remote communication for OpenVPN client devices (See "VPN Remote Access with IP Routers" below.) OpenVPN, a well-supported open-source VPN technology, incorporates SSL/TLS security with encryption.
EIPR RoutersFast Speeds and Higher Data Throughput
The EIGR Gigabit IP Routers have features beyond our popular EIPR series, while retaining the EIPR's ease-of-use. The EIGR adds Gigabit speed on both LAN and WAN ports for faster routing and higher data throughput. The EIGR-V router adds OpenVPN server capability. Some models provide wide-temperature operation, from −40°C to +75°C.
EIGR RoutersIP Protocol with Cellular Communication
The EIGR-C Gigabit IP routers offer the same capabilities as the EIGR with a built-in cellular modem for easy connectivity to cellular networks. The EIGR-C3 is approved for use on the Verizon network and can be used at sites where wired connectivity is an issue. The EIGR-C2 is approved for use in Europe.

VPN Remote Access with IP Routers
RemoteVPN is a service offered by Contemporary Controls that allows systems integrators remote access to systems from the convenience of the systems integrator's home or office. A cloud-based VPN server hosted by Contemporary Controls provides the critical connection between two VPN clients—one installed on the systems integrator's PC and the other permanently installed on Contemporary Controls' EIPR/EIGR VPN router located at the remote location. Using this approach, two secure VPN tunnels are created with no concern for intervening firewalls. In addition to OpenVPN PC clients for Windows machines, OpenVPN clients are available for iOS and Android mobile devices for greater flexibility in accessing sites remotely.
- Wired or wireless operation over the Internet
- Secure communication tunnels utilizing encryption
- No capital investment in resident VPN servers
- Free download of OpenVPN Windows PC client software
- Support for iOS, Android and Linux OpenVPN clients
- Applicable to both permanent and temporary remote access
- Flexible man-machine and machine-machine applications
- Quick realization of a remote access project
- Simultaneous access to multiple remote sites
