# Networking

The last step before proceeding with the configuration of PlexusLab is the management of the connection to the I/O devices.

Make sure you have at least one I/O device for which you know the IP address before proceeding with the setup via the platform. Each device of the Plexus POD series offers the possibility to manually set its own IP; refer to the POD user manual for more information on this.

It is good practice to assign a subnet to the section that connects the Plexus Lab web server with the I/O devices, as in the following examples. Tip

More complex networks, composed also or only of I/O devices not of the Plexus PODs series, are listed among the advanced examples; in these cases it is necessary to refer to the chapter on configuring the ModBus API.

# Basic configuration examples

Below are some examples of networks made up of a PlexusLab Web Server and different combinations of connected I/O.

# 1 Plexus POD

Web Server and PlexusLab + 1 Plexus POD.

A configuration of this type, a simple configuration, allows you to have a simple monitoring on your system thanks to the inputs and outputs provided by the Plexus POD.

1-pod
PlexusLab address: 192.168.1.100/plexus/
Plexus POD device's address: 192.168.2.200

# 2 or more Plexus PODs

Web Server with PlexusLab and 2 (or more) Plexus PODs.

A configuration of this type allows you to extend the number of sensors and actuators connected to the system thanks to the use of more than one Plexus POD.

2-pods
PlexusLab address: 192.168.1.100/plexus/
Plexus POD devices' addresses: 192.168.2.200, 192.168.2.201, ...

# Multi-server configuration examples

Below are some examples of networks made up of more than one PlexusLab Web Server and different combinations of connected I/O.

# 2 Plexus Lab autonomous

2 Web Server with PlexusLab with its associated PODs (as seen below for basic network configurations), without any virtual link between the two.

This configuration is in effect a basic configuration, replicated on more than one server.

PlexusLab address 1: 192.168.1.100/plexus/
PlexusLab address 2: 192.168.1.101/plexus/

# 2 Plexus Lab, including 1 bridge

2 Web Server with PlexusLab, one of which is in Bridge mode, plus the related associated PODs (as seen for the basic network configurations).

A configuration of this type, once the setup on both Web Servers is complete, allows you to monitor the entire system from the PlexusLab platform installed on the "master" machine.

The image below is on adding I/O devices explains in detail how to add a Plexus Bridge.

PlexusLab address 1: 192.168.1.100/plexus/
PlexusLab address 2: 192.168.1.101/plexus/
