The hub-and-spoke tree topology of Ethernet makes it very easy to add and remove devices without upsetting the operating network. Because FOUNDATION HSE is based on unmodified Ethernet, standard Ethernet tools can be used for installation qualification, testing, and troubleshooting. These tools speed up the resolution of communication problems. FOUNDATION HSE is supported by better troubleshooting tools not available for RS485 and coax. Since FOUNDATION HSE is based on UDP and TCP, standard network management tools employing SNMP, RMON, etc., can be used. Similarly, familiar IP addressing is used including support for DHCP.
