GE PACSystems RX7i, RX3i and RSTi-EP  TCP/IP Ethernet  Communications

Ethernet Interfaces for PACSystems Controllers

A PACSystems Ethernet Interface enables a PACSystems controller to communicate with other PACSystems  equipment and with Series 90 and VersaMax controllers. The Ethernet Interface provides TCP/IP  communications with other PLCs, host computers running the Host Communications Toolkit or CIMPLICITY  software, and computers running the TCP/IP version of the programming software. These communications use  the proprietary SRTP and Ethernet Global Data (EGD)1 protocols over a four-layer TCP/IP (Internet) stack.  The Ethernet Interface has SRTP client/server capability. As a client, the Interface can initiate communications  with other PLCs that contain Ethernet Interfaces. This is done from the PLC ladder program using the  COMMREQ function. As a server, the Ethernet Interface responds to requests from devices such as PLC  programming software, a Host computer running an SRTP application, or another PLC acting as a client.

▪ Direct connection to BaseT (twisted pair) network switch, hub, or repeater without an external  transceiver. 

▪ Protocol is stored in flash memory in the Ethernet interface and is easily upgraded through the CPU  serial port. 

▪ Communications with remote PLCs and other nodes reachable through routers. The gateway IP  address must be configured. 

▪ Internet access via web pages served up to standard web browsers, for the Ethernet interface  embedded in the PACSystems RX7i CPU.

CPE330/CPE400/CPL410

• Two independent 10/100/1000 Ethernet LANs under the control of the embedded RX3i PLC. Port 1  attaches to LAN1 through a dedicated RJ45 connector. Port 2 attaches to LAN2 through a pair of  internally-switched RJ45 connectors. Space is provided to mark in the two corresponding IP  addresses. 

• The embedded Ethernet interface permits the CPU to support two LANs. 

• CPE400 has a third Ethernet port (located on the underside) which is under the control of Field Agent. 

• CPL410 also has a third Ethernet port (located on the underside) which is under the control of the  Linux OS.

RSTi-EP CPE100/CPE115

• Two independent 10/100 Ethernet LANs. Port 1 attaches to LAN1 through a dedicated RJ45  connector. Port 2 attaches to LAN2 through three internally-switched RJ45 connectors.  

• The embedded Ethernet interface permits the CPU to support two LANs.
