NOTE: In this release, the Service port and the Sync Link port are enabled.
Part No.: 4417591_Rev10
Introduction
TABLE 1-2 provides a description of each port.
Description of the Ethernet ports
Ethernet port Description
Service port The Service port is used to set up a point-to-point connection
between the CIU 888 and a service laptop/PC, allowing service
technicians to configure the CIU 888 including field instruments
connected to the CIU 888, and to perform system diagnostics.
The Service port is also used to perform firmware upgrades and
to view/updated the license of the CIU 888. The service port is
conveniently located at the front of the CIU 888 for easy
access.
Sync Link port The Sync Link port is used as dedicated, private synchroniza-
tion link (point-to-point) between two CIU 888s in a redundant
system setup. Continuous data synchronization between the
CIUs guarantee highest data availability.
VPN port The VPN port is intended to be used to set up a secure point-to-
point connection to provide remote access enabling off-site ser-
vice and diagnostics of CIU 888 and gauges. This port is
enabled with configurable IP address for local servicing of CIU
888 and gauges. The remote access enabling off-site service
and diagnostics of CIU 888 and gauges will be enabled in future
releases.
FTE ports The FTE (Fault Tolerant Ethernet) ports are intended to be used
to set up individual connections between the CIU 888 and host
systems such as PLCs and DCSs. The FTE ports can also be
used combined to support an FTE connection with Experion. By
providing multiple communication paths between nodes
(servers and stations), FTE tolerates more faults, i.e. all single
faults, as well as many multiple faults. FTE ensures a rapid
response in case of communication failures with minimal
switchover time. Ethernet nodes with no FTE hardware or
software can be connected to the FTE control network and
benefit from its highly available communications environment.
Office LAN port The Office LAN port is intended to be used to connect the
CIU 888 (and the control network it is part of) to the business
network of the site in order to securely share data with office
applications, thereby saving costs on operation and data
exchange.
Network segregation is supported by the CIU 888 - a software-based
firewall ensures that only the required socket ports are opened for each
enabled Ethernet port. The firewall monitors and identifies all incoming
and outgoing network traffic and blocks all unwanted network traffic.
