The FIO (Fieldnetwork I/O) System is connected to the Field Control Unit (FCU) via an ESB, optical ESB, or ER
bus.
The Field Control Unit (AFV30/AFV40) is connected to an ESB Bus Node Unit (ANB10) or an Optical ESB
Bus Node Unit (ANB11). The Field Control Unit (AFV10) is connected to an ESB Bus Node Unit (ANB10) or
an ER Bus Node Unit (ANR10).
A node unit consists of a power supply module, a bus interface module, and input/output modules that are installed
in a base unit. The power supply module, bus interface module, and input/output modules can be configured
redundantly.
The Unit for Optical ESB Bus Repeater Module (ANT10U) can be used to connect the optical ESB bus in a chain or
star configuration.
The following shows a system configuration example
