1. General Introduction
EC401 ESB Bus Coupler Module installed on Field Control Unit for signal communication between Field Control Unit and the ESB Node Unit. For the dual-redundant configuration of the processor modules, EC401 must be installed in both slot 7 and slot 8 of Field Control Unit; for single configuration, EC401 must be installed in slot 7 of Field Control Unit and keep slot 8 empty. By installing two modules in the Field Control Unit for FIO, dual-redundant ESB bus can be configured.
