the configurations described above before using the site configuration in the
CIU 888. If the existing site configuration is not in one of these configurations
(e.g. a single CIU Plus two CIU Primes or multiple CIU Pluses and/or
CIU Primes configured in the same site database), the site configuration needs
to be manually edited to match one of these configurations. Another option
could be to create a copy of the existing site configuration and then delete the
site elements not required to be imported. It is, of course, necessary that the
mechanical and electrical installation is also adjusted so it will match the
changed site configuration.

3.3.1.1 Redundant pairs of CIU Plus and CIU Prime with a single host system

In this topology, two pairs of CIU Plus and CIU Prime are configured in a
redundant setup with corresponding host ports, field ports, tanks and
gauges. Both pairs are connected to one and the same host system (i.e.
Entis Pro). Each pair is connected to the host system via one of the four
host ports of the CIU Plus.
