Introduction

1.7 Maximizing data availability through full redundancy

Operations for inventory control and custody transfer rely on accuracy,
reliability and availability of the tank gauging system. By setting up two
CIU 888s in a redundant system setup, system reliability and availability
can be increased even more. Continuous data synchronization and host
initiated switchover ensures highest data availability and smooth
transition between CIUs, with minimal interruption of critical applications
and services.

1.8 Remote access for safe and secure support of gauges

The CIU 888 is the interconnection between gauging instruments in the
field and service tools, such as Honeywell's Engauge and Rosemount
TankMaster, in the site control room. All Honeywell gauging instruments
communicating via GPU/Flexconn protocol/TRL/2 can be accessed and
configured remotely via the CIU 888 in a safe and secure way, enabling
site support and more efficient commissioning. In a similar manner, the
Emerson TRL/2 devices (e.g. Rex gauges) can also be accessed and
configured remotely via the CIU 888.
