2.3 Legacy RTU to Substation LAN Gateway
IED’s are beginning to be available with Ethernet connections via 10/100BaseT or
100 Base FX. The ePAQ-9100 can be configured with an Ethernet interface that
supports both 10/100 Base TX or 100 Base FX. The Ethernet Interface supports both
UCA 2.0 (OSI and TCP/IP) and DNP3 over TCP/IP. Data from existing Legacy RTU, as
well as IED’s with serial communications interface, can be added to the LAN. See block
diagram below.
