Cep Carrier; Cep Expansion Carrier - GE PACSystems RX3i User Manual

Chapter 1. Overview

1.1 CEP Carrier

The RX3i CEP Carrier (IC695CEP001) interfaces a remote node of one RX3i I/O module to a PROFINET I/O Local
Area Network (LAN).
The RX3i CEP Carrier works as a PROFINET Scanner. It scans the I/O modules installed on it and, if present, the
RX3i CEP Expansion Carrier, retrieving input data and providing output data, and exchanges that data on the
PROFINET I/O LAN at the configured production rate. It also manages PROFINET communication and module
configuration between an I/O-Controller and modules in the remote node. If network communications are lost,
the RX3i CEP Carrier manages I/O states according to the individual module configurations.
The RX3i CEP Carrier supports 10/100 Mbps Ethernet communication. Although PROFINET communications
only work with 100 Mbps link speed, 10 Mbps can be used for other types of Ethernet traffic such as PING.
RX3i CEP Carrier features include:
•
Full programming and configuration services for all supported RX3i I/O Modules using Proficy Machine
Edition
•
Supports daisy-chain/line, star, or ring (redundant media) network topologies
•
Two switched Ethernet ports: two eight-conductor RJ-45 shielded twisted pair 10/100 Mbps copper
interfaces
•
USB port for field updates of firmware using WinLoader
•
Supports Hot-Standby CPU Redundancy using PROFINET I/O (requires RX3i CEP001 2.01 GSDML to
version 2.3 or later)
•
Supports HART
®
Note: The CEP Carrier requires a user-supplied +24 Vdc power source.

1.2 CEP Expansion Carrier

The RX3i CEP Expansion Carrier is attached to the RX3i CEP Carrier and provides the ability to add one
additional RX3i IC694 I/O module to the remote node. It is used only with an RX3i CEP Carrier, which performs
I/O scanning of the Expansion Carrier. The RX3i CEP Expansion Carrier does not have Ethernet or USB
interfaces, nor does it require an external power source
