Description
The ER Bus Interface Master Module is the communication module to connect the ESB Bus Node Unit (Local Node) or the Compact Field Control Unit (for FIO) with the ER Bus Node Unit (Remote Nodes) using ER bus.This module can be installed in the ESB Bus Node Unit (ANB10S, ANB10D) and the Compact Field Control Unit(for FIO) (AFF50S, AFF50D, AFV10S, AFV10D).By installing two modules of these in the ESB Bus Node Unit or the Compact Field Control Unit (for FIO),dual-redundant ER bus can be configured.
