Introduction

1.5.2 Serial host ports

To support existing applications, the CIU 888 has two fixed serial
(RS-232/RS-485) host ports, as shown in FIGURE 1-8.

These serial ports can be used to connect hosts with the CIU 888 using
modbus RTU. The 100% compatibility with the CIU 880 interface
ensures a smooth migration of existing applications. Other modbus
mapping is also possible to support other data to be transferred.
Alternatively, any host port can be configured to support the standard
CIU 858 protocol and ensures to provide backward compatibility.

1.5.3 Ethernet host ports

CIU 888 supports ethernet connectivity to Tank Inventory systems via
FTEA, FTEB and Office LAN ports as shown in FIGURE 1-9.

These ethernet ports (FTEA, FTEB, Office LAN) can be used to connect
hosts with the CIU 888 using Modbus TCP/IP. Modbus maps supported
by ethernet host ports is same as that of serial host ports.
