Wired and wireless IP routers

   

Wired and wireless IP routers

Many manufacturing facilities are executing asset digitization projects incorporating Industrial Internet of Things (IIoT) connectivity between devices. In many instances, plant-wide and machine-to-machine communication using an Ethernet-based protocol is the norm. Machines are utilizing Ethernet for internal communication between components as well. PLCs, HMIs, Industrial PCs, variable frequency drives, etc. are commonly communicating via the Ethernet protocol.

Problems arise when machines are added to a larger network or asked to communicate peer-to-peer. One of the issues is the question how to keep and reuse the addresses and programming within the machine control system, which may conflict with other addresses on the network. It can also be difficult to interface the machine network to a wider area network, or to to remotely access the machine for programming, diagnostics, and troubleshooting.

The EIGR / EIPR Skorpion family of IP routers is designed to offer a solution to all these needs. The EIPR links two 10/100Mbps Internet Protocol networks, passing appropriate traffic while blocking all other. The EIGR provides the same functions at Gigabit speed. Both units feature a 4-port Local Area Network (LAN) where the machine components interact and a single-port Wide Area Network (WAN) that connects to the factory network. A built-in firewall prevents unauthorized access to the LAN side devices from the WAN side but included router features such as Port Forwarding and Network Address Translation (NAT) allow for WAN to LAN access.

The WAN port can be configured for a static IP address or assigned a dynamic address via the built-in DHCP client to quickly integrate to the plant network. The IP router also keeps multicast and broadcast traffic separated between the LAN and WAN, allowing the machine network to run smoothly without having to deal with unnecessary traffic filtering. Additionally, by using the EIGR-V / EIPR-V models, remote access to the machine from the Internet via Virtual Private Networking (VPN) technology is available.

The same configuration can be used across multiple machines. This accelerates testing while being built, as well as on-site installation where just the WAN IP address must be configured. Skorpion IP routers have been successfully used in varied industries such as Transportation, Robotics, Automated Guided Vehicles (AGVs) and more.
