发明名称 BUILT-IN ETHERNET SWITCH DESIGN FOR RTU REDUNDANT SYSTEM
摘要 A system includes a remote terminal unit (RTU) controller module (202a). Each RTU controller module comprises a controller board (614a) configured to couple to a carrier board (602) that includes first and second Ethernet ports (628a-628b). Each controller module comprises computer processing circuitry (518a) including the first and second MACs (532-534) and configured to select to transmit a packet to the first Ethernet port through the first MAC and to alternatively select to transmit the packet to the second Ethernet port through the second MAC. Each controller module comprises an Ethernet switch (504a) configured to receive the packet from the first media access control (MAC) and transmit the packet to the first Ethernet port. Each controller module comprises a physical Ethernet interface (PHY) (522a) configured to receive the packet from the second MAC and transmit the packet to the second Ethernet port. The computer processing circuitry, the Ethernet switch, and the PHY are mounted on the controller board.
