Configure The Rmc For 1 Network Mode (2-Port Switch); Remote Access To Rmc By Host (Connections) - ABB RMC-100 User Manual

For full configuration, follow the procedure that applies to the required topology and Ethernet mode.
See sections

4.6 Configure the RMC for 1 Network mode (2-port switch)

2 Network mode.
IMPORTANT NOTE: The RMC default Ethernet mode is 1 Network (2-port switch mode). The
Ethernet ports are disabled by default.
IMPORTANT NOTE: If you are connected to one of the Ethernet ports to configure the RMC-100,
changing the Ethernet configuration and restarting the interface will cause you to lose connection.
Make sure to configure your laptop with an IP address compatible with the new IP address assigned
to the RMC. Re-establish connection using the new RMC IP address after the device restarts.
4.6 Configure the RMC for 1 Network mode (2-port
switch)
The RMC supports switching capability and can behave as a 2-port switch. This mode of operation is
the factory default and is displayed as: 1 Network, in the Mode field on the PCCU Networking tab
screen.
The 1-Network mode simplifies IP parameter configuration, especially in installations with multiple
ABB devices. The local field LAN switch, the RMC-100, and any additional devices, can be configured
for and communicate through a single subnet. This mode supports remote and local access to both the
RMC and attached devices without the need of additional routing equipment on the field.
IMPORTANT NOTE: When the RMC is in 1 Network mode (2-port switch), never connect the
Ethernet ports to an external Ethernet switch at the same time
same switch in this mode causes loss of connections to the device. Connect only one port to the
switch.

Remote access to RMC by host (connections)

Figure 4-17 shows remote access through the customer wide area network. Use either Ethernet port
to connect the RMC to the field network switch. The RMC's IP address is a non-default generic number
as an example. The subnet address the RMC is configured for is represented by "ZZZ". The address
remains the same whether the RMC is connecting using Ethernet port 1 or 2.
