important
that the bus both devices terminated the beginning and the end the network.
All the bus segments have terminated for 4-wire connections. The left E-LAN sends the signal through 4-wire
connection the next device that connected the E-LAN.5 E-LAN (bus connection between several devices)

Figure 73: Networking with E-LAN: 2-wire bus
The above figure shows the most commonly used networking configuration. AA: Sends the parameters the connected
device.
– Four-wire
A 2-wire connection sufficient for short connections (within substation, m). Distances 1.Page Detailed description REG-DP/ REG-DPA parameters
We take care it.
A 4-wire connection recommended for longer distances.2.
The required resistors are already the regulator and are switched and off through
a relay.
.
0 Baud:
The transfer rate can set for each segment.
The 'Terminated' parameter should set for all the devices in-between.2.3 can bridged.
11.4 <Send AA:>
Click the button transfer the parameters.
For 2-wire connections, termination depends the bus structure: select YES (for
closed/terminated) (for not closed/not terminated). This wiring enables the
regulator function repeater.
11. Meaningful speeds are:
– 500
– 125 000
0 Terminated:
If regulator the beginning end bus segment, the bus must be
closed/terminated that point with resistor (wave impedance). this case, the right E-LAN, for
example, used input for the signal
