Free guide to Internet Protocol (IP) for control networks

Contemporary Controls is offering engineers a valuable document on the IP (Internet Protocol) portion of the TCP/IP stack as it applies to control networks. This document, ABCs of the Internet Protocol, defines TCP/IP and other topics, including data encapsulation, routers and hosts, IP addressing and the IP header.

Free guide to Internet Protocol (IP) for control networks

The IP is responsible for the end-to-end delivery of datagrams over an Internet. It also provides host and network addressing and the means for fragmenting datagrams into manageable packets. IP is a routable protocol and much of its complexity is due to its ability to route packets directly within a local network or indirectly through routers. Routers are not ideal for a control network, since they reduce determinism and increase data latency.

Still, to accept TCP as a transport layer for an Ethernet control network requires acceptance of IP as well. By understanding the limitations of IP, an engineer can still design a control network using the TCP/IP family of protocols. This is especially true if the control network is restricted to that of a private or local network.
