RCDP

You configure RCDP (RUGGEDCOM Discovery Protocol) on the page "System >
Configuration".
If RCDP is configured accordingly on the device, you can access the device with the
RUGGEDCOM EXPLORER via out-of-band interface.
RUGGEDCOM EXPLORER
With the RUGGEDCOM EXPLORER you can recognize devices in a network and make the
following basic settings:
● IP Address
● Subnet Mask
● Default Gateway
● System Name
● Device Location
● System Contact
The RUGGEDCOM EXPLORER can run on every LAN-based MS Windows-PC.
You will find more information on the RUGGEDCOM EXPLORER here:

VLAN

4.4.1

Basics

Network definition regardless of the spatial location of the nodes
VLAN (Virtual Local Area Network) divides a physical network into several logical networks
that are shielded from each other. Here, devices are grouped together to form logical groups.
Only nodes of the same VLAN can address each other. Since multicast and broadcast frames
are only forwarded within the particular VLAN, they are also known as broadcast domains.
The particular advantage of VLANs is the reduced network load for the nodes and network
segments of other VLANs.
To identify which packet is assigned to which VLAN, the frame is expanded by 4 bytes (VLAN
tagging (Page 38)). This expansion includes not only the VLAN ID but also priority information.
