Chapter 1. IntroductionGFK-2224Q January 2017 7Connector CPE305 & CPE310: One RJ45CPE330: Three RJ45CPE400: CPE400: Six RJ45, five on front for three LANs (LAN3 future), one EFAunderneath. (There is also an unused serial RJ45 underneath.)LAN IEEE 802.2 Logical Link Control Class IIEEE 802.3 CSMA/CD Medium Access Control 10/100 MbpsCPE305 & CPE310 has one 10BaseT/ 100BaseTX PortCPE330 has two independent 10/100/1000 Mbps Ethernet LANs:▪ The top Ethernet Port attaches to LAN1 using a dedicated RJ45 connector▪ The bottom two Ethernet Ports attach to LAN2 using a pair of internally-switched RJ45 connectorsCPE400 supports four independent 10/100/1000 Ethernet LANs. Three arelocated on the front panel.▪ LAN1 attaches via the upper, dedicated RJ45 connector.▪ LAN2 and LAN3 (future) each attach via a pair of internally-switched RJ45connectors.▪ The fourth LAN, labeled EFA (Embedded Field Agent), is located on theunderside, and is specifically used for Field Agent connectivity.Number of IP addresses CPE305 & CPE310: OneCPE330 has two IP addressesCPE400 has four IP addresses (one for EFA, three for Ethernet LANs)Maximum number ofconnectionsFor CPE305 & CPE310:▪ 32 SRTP Server connections, includes:o Up to 16 Modbus/TCP Server connectionso Up to 32 Client channels. (Each channel may be an SRTP Client ora Modbus/TCP Client. Any given channel can be assigned to onlyone protocol at a time.)▪ OPC UA Server with support for up to 5 concurrent sessions with up to 10concurrent variable subscriptions and up to 12,500 variables▪ Up to 255 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.For CPE330, the embedded Ethernet permits the CPU to support two LANswhile the CPE400 supports LAN1, LAN2 and LAN3 (future) with:▪ Up to 48 simultaneous SRTP Server connections, and▪ Up to 16 simultaneous Modbus/TCP Server connections▪ Up to 32 Clients are permitted; each may be SRTP or Modbus/TCP▪ OPC UA Server with support for up to 5 concurrent sessions with up to 10concurrent variable subscriptions and up to 12,500 variables▪ Up to 255 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.
