ET 200 Distributed I/O System
EWA 4NEB 780 6000-02a
The speed of data transmission, expressed as the number of bits transferred
per second (baud rate = bit rate).
ET 200 supports baud rates from 9.6 kbaud to 12 Mbaud.
If, after exporting data to a memory card, you wish to save this data on the
PG/PC as well, you must create a binary file. Like the memory card, the
binary file contains all the bus, slave and master parameters of a bus system
configured with COM ET 200 Windows.
Common transmission path interconnecting all nodes; the bus has two
defined terminating points.
The bus for the ET 200 system is a two–conductor cable or a fiber–optic
waveguide.
Physical connection between a station and the bus.
Bus connectors for ET 200 are available with and without interface for the
programmer and with IP 20 and IP 65 protection ratings.
Segment
The set of all stations physically connected by a bus cable forms a bus
system.
An operating mode of the DP master. The DP master reads the input data
cyclically, the outputs remain set to "0".
The DP master participates in the token ring.
The act of parameterizing individual modules in a distributed I/O system
and/or assigning addresses.
