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:
