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. RJ-45 female connector (shielded). There are two integrated
LEDs indicating the current communication status. The LEDs
are not labeled but can be identified by their color. The upper
yellow LED indicates the transmission rate, the lower green
LED indicates the communication state.
