2.3.1.2 Single pair of CIU Plus and CIU Prime

In this topology, a single pair of CIU Prime and CIU Plus is connected to
a host system (i.e. Entis Pro) via one of the four host ports of the
CIU Plus (see FIGURE 2-8). A configured host port has its own unique
RTU address and enables Modbus on serial communication.

On the CIU Prime, a maximum of four field ports are available to
connect to tank gauging instruments. The field ports can be configured
for GPU on Bi-Phase Mark communication or GPU on serial
communication.
The CIU Prime and the CIU Plus are connected to one another via one
of the host ports of the CIU Prime and one of the field ports of the
CIU Plus.

2.3.2 Mapping of host ports

Ensite Pro allows users to configure the four CIU Plus host ports and
the two CIU Prime host ports, whereas the CIU 888 features two fixed
host ports and two flexible host ports (i.e. option slots 5 and 6 can be
configured as host port).
