6.3 Description of the NET-PARAMETERS
The NET parameters described below can be found in the
NET PARAMETERS menu:
▶
Simultaneously press the DEL and ALT buttons with the status display
active. Then choose CONFIGURATOR -> NET -> NET PARAMETERS and
press the OK button.
Station number (Station Menu NET-ID)
Default settings NET ID = 00.
Selectable, valid NET-IDs 01 - 08.
The NET ID of a device is used to give it a unique identification on the NET.
A NET ID can therefore only be assigned once within a network.
The default setting NET ID 00 prevents the possibility of double addressing
when an existing NET station (NET ID 1 - 8) has to be replaced.
Data transfer speed (Station Menu BAUD RATE)
Factory set baud rate = 125 Kbaud.
The devices allow a NET transfer speed of 10 - 1000 Kbaud, selectable in
defined steps. Possible baud rates are: 10, 20, 50, 125, 250, 500 and
1000 KB.
▶
Use Í and Ú to select a baud rate of 10 - 1000 Kbit/s and confirm your
selection with OK.
The maximum transmission speed depends on the total length of the
network cables (a Technical data,
￫
Section 12.3.7, “NET

network“ on
Page 359).
￫
All NET stations must have an identical transfer speed set.
This is achieved automatically if you carry out the NET
con
fi guration via NET station 1 (
￫
section “Configuring NET”,
page 94).
￫
The reaction speed of devices connected via the NET depends
essentially on the baud rate, the delay time and the volume of
transferred data.
Therefore always set the maximum transfer speed. The factory
set baud rate depends on the total length of the network cables
of 125 m.
A maximum baud rate is therefore very important if an MFD is
required to work on the NET since additional NET transfer time
is needed.
