Description 

The FI 840F is a high speed ethernet fieldbus module designed for fast data exchange in production engineering with decentralized peripherals. 

The FF/HSE module FI 840F is a Fieldbus-Foundation®-(FF)-Master. Using the Control Builder F it is possible to configure diverse Fieldbus Foundation®-devices. 

The FF/HSE module FI 840F is designed to connect the AC 800F to a FF/HSE network. It can be mounted on slots F1 ... F4. It is used if high transmission rates are required or shall be made available for future use. FF/HSE wiring is always a point-to-point connection. Therefor a networks with more than two nodes always requires network switches or hubs.
