Yokogawa EB501

Product Dimensions：

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.
