PROmesh P20 against additional heat radiation and observe the approved temperature range for
storage and operation.
2.3 Voltage supply connection and fault relay
Operate your PROmesh P20 with a nominal voltage of DC 12 V to 48 V. To safeguard your system
availability, connect the redundant supply circuits VDC1 and VDC2 with the appropriately marked terminals
of the supplied 7-pin terminal block adapter (VDC1, GND, as well as VDC2, GND). The voltage needs to
be an SELV/LPS-compliant voltage in acc. with IEC 60950-1 / EN60950-1 / VDE0805-1.
Always make sure that all connections are connected in the correct order, in accordance with the technical
specification on page 55.

2.5 Network integration and commissioning
2.5.1 Data ports
The PROmesh P20 is equipped with 20 data ports, which enable data transmission in compliance with the
PROFINET-IO standard, with up to 100 Mbps in acc. with the 10Base-T and 100Base-Tx (RJ45) standard,
as well as up to 1000Base-X (SFP). The actual baud rate is automatically detected and regulated depending
on the network device. MDI/MDI-X Autocrossover has to be crossed appropriately, so that connections can
be established to other devices independently from the cable type used (1:1 or crossed). MDI/MDI-X
Autocrossover can be deactivated by means of the web management.
The four SFP slots are used to install Mini GBIC SFP transceiver modules and thus make flexible integration
with the media type that you need possible (copper, multi-mode fibreglass, single-mode fibreglass).
If a suitable SFP transceiver is installed at the SFP slot, the configuration of the transceiver can be
monitored and adapted via the Web-Based Management (WBM) of the PROmesh P20.
The PROmesh P20 fully supports all media types and associated functions of the PHY layer and
LNK layer, also via the four SFP slots.
Take care to select appropriate SFP transceiver modules and appropriately assigned line layouts
when connecting the SFP transceiver modules, to ensure that all functions for your media
integration, such as e.g. half-/full-duplex mode, can be used.
2.5.2 Media selection and connection
In addition to the 16 data ports for connecting RJ45 copper lines, the PROmesh P20 is equipped with four
additional data ports for connecting Mini GBIC transceiver modules in acc. with the SFP INF standard.
This makes it possible to flexibly integrate the PROmesh P20 into your automation network by using
different media types, such as copper lines, single-mode fibreglass lines and multi-mode fibreglass in
duplex mode.
When laying out, selecting, assigning and assembling your data line, pay attention to the pertinent
standards and make sure fixed connections are used for applying the connectors; this is necessary in order
to ensure the max. possible line lengths and cascading of network segments in acc. with your media type
(copper, optical fibres, etc.).

Device ports and status indicators
PROmesh P20 - User Manual 15
2.5.3 Cabling
To connect your PROmesh P20 via the equipped RJ45 data port, use twisted-pair cables, Cat 5
or higher, with a max. line length of up to 100 m. The actual line length has to be limited
depending on the project planning and commissioning, as well as the attenuation values
measured locally when setting up your network topology. To improve the shield termination, we
recommend the RJ45 PROFINET connector of Indu-Sol.

PROmesh P20 - User Manual 16
2.6 Network topology and media redundancy
Using the PROFINET application in your automation network makes it possible to flexibly integrate and
configure devices in your PLC domain, based on the Ethernet protocol.
This not only enables a higher data data throughput, but also makes it possible to distribute and integrate
the network devices among each other along different paths. A network segment in Ethernet-based
networks thus spans between each device pair.
Switches such as the PROmesh P20 thus play a key role in your automation network and should be suitable
for use in different network structures, to allow flexible expansion and adaptation of your system structure.
The PROmesh P20 makes it possible to achieve this expediently and conveniently, as it offers extensive
functions for networking and securing the communication of all network devices within the PLC domain.
2.6.1 Network topology
Typical Ethernet star structures (see Figure 5) can be networked with the PROmesh P20 switches without
further configuration. The devices are operable immediately.
In comparison to basic fieldbus systems, the PROFINET application allows MxN connection of all devices,
based on an Ethernet network structure, and thus enables direct network communication between two
devices. Basic meshing is described as a star structure (see Figure 6) in which each device can exchange
information with the other network devices via a central distributor. If the network structure is expanded by
meshing several star structures, a media-redundant multi-channel communication can be set up between
two devices. This increases the fail safety of the automation system significantly.
Here the switch, as a central element for forwarding this information, plays the key roll in forwarding data
to the appropriate receiver unchanged and with as little delay as possible. Additionally, the communication
should be restricted to one propagation path, to limit the strain on the line capacity that occurs in the case
of multi-path propagation.
The PROmesh P20 supports you in the task of setting up a slimline, expandable and efficient network
structure for your PROFINET domain.
In addition to full integration into the PROFINET domain, the PROmesh P20 can be subjected to a load of
up to Netload Class III (network limit).
Additionally, the PROmesh P20 supports the use of redundancy functions for intermeshed structures as
well.
Depending on the existing intermeshed structure in the PLC domain, different protocol functions have
shown to provide varying levels of performance and suitability.
The PROmesh P20 supports the following redundancy functions for preventing multi-path propagation of
the data communication in standard cases and to define an alternative route as fast as possible in the event
of an error.
The following protocols are supported by the PROmesh P20.

2.7 Ring structure
Ethernet-based networks make it possible to set up ring structures. These are characterized by each device
being able to forward data in the form of Ethernet packages to the other network devices along at least two
physical paths.
Using this network structure in your PROFINET domain thus makes it possible to establish redundant
availability of all network devices if a connection between two devices of the ring structure should be
interrupted.
The industrial Ethernet switch plays a key role in the implementation of a redundant network structure, by
logically restricting the forwarding of data of all network devices to only one path and switching over to the
alternative forwarding path in the event of an error. Thus unambiguous communication, low netload and
simple media redundancy are all safeguarded simultaneously. Within the scope of the PROFINET standard,
it is recommended to set up ring structures based on the MRP protocol (as per IEC 62439), to identify a
secured interruption of ring structures in the PLC domain, as well as the associated switchover, and react
to it through technical measures.

Device ports and status indicators
PROmesh P20 - User Manual 18
The PROmesh P20 fully supports the IEC 62439 standard and enables deterministic convergence of the
information forwarding with simple redundancy (ring topologies, see Figure 7). Depending on your system,
convergence times of max. 200 ms (500 ms) thus becomes possible.
Figure 6: PROmesh P20 in a ring-shaped network
2.7.1 Ring redundancy
The PROmesh P20 makes it possible to set up simple ring redundancies, as described in Section 2.7.
The following function protocols are used to set up ring structures.
2.7.1.1 Netload balancing
In the meshed networking of subnetworks, specific connections frequently have high data traffic.
It is particularly noticeable that this data traffic frequently takes the form of load peaks in the
communication and thus it is difficult for system operators to calculate it. To ensure fail-safe operation
of the automation system, unlimited data forwarding is required even under these conditions.

Web application
PROmesh P20 - User Manual 19
The PROmesh P20 supports the application of aggregated network resources, i.e. the logical coupling
of several physical connections to a logical connection. With this, an optimal netload distribution is
enabled for selected connections with high data traffic and the physical bandwidth of a connection is
expanded logically in the event of a high load. To this end, the PROmesh P20 can be configured using
the link aggregation protocol.
2.7.1.2 NAT routing
Industrial networks are characterized by integration of all communication devices within one PLC
domain.
As the meshing of these (sub)networks increase, it becomes increasingly necessary to handle
monitoring and control tasks that are not within the operational level of the automation system.
The basis for achieving these tasks is that a connection has to be established between different address
areas in the Ethernet-based communication. Simultaneously, access to important resources and
network resources within the automation task is to be strictly prevented.
Therefore, the PROmesh P20 has been equipped with complete Layer-3 support, as well as NET
routing functionality with basic firewall properties.
Network devices within the LAN automation environment are thus efficiently protected against access
of network components that are outside of this environment. Simultaneously, a defined gateway
becomes possible through the introduction of NAT rules.
Filtering based on the blacklist procedure therefore only allows connections that have been clearly
defined in advance.
To also support this characteristic physically, access to the automation network is limited to network
components with connection to Port 20 of the PROmesh P20.
For more characteristics and properties for configuring the NAT functions, refer to Section 3.9 of this
manual.
3 Web application
The PROmesh P20 switches are equipped with a modern web interface by which they can be conveniently
configured from any web browser.
3.1 Preparations
Install the PROmesh P20 switch in the network before you use the web management and make sure that
the PC intended for the configuration of the switches can access the switch via the web browser. Connect
the PC to one of the data ports with a suitable data line (P1-16, G1-G4). The PROmesh P20 and the client
PC to be connected have to be in the same IP address range and IP subnetwork. To this end, you first
have to assign an appropriate IP Address to your PROmesh P20.

Web application
PROmesh P20 - User Manual 20
In delivery status of the device, the following IP address, subnet masks, administrator user name and
administrator password have been set:
IP address: 0.0.0.0
Subnet mask: 0.0.0.0
Gateway: 0.0.0.0
User name: admin
Password: admin
It is mandatory to change the factory default password immediately after the first log-in. It is your
responsibility to document this password and protect it against unauthorised
access.
The setting of your intended user addresses can be conducted easily with the Indu-Sol ServiceTool. This
is available for download, free-of-charge from the following link:
https://www.indu-sol.com/servicetool
Our software is updated regularly. Make sure that you have the current version.
After installing and opening the software, establish a network connection from your computer to one port of
the switch and scan the system with the search setting PROFINET device. Afterwards, you can enter and
save the corresponding entries in the input mask.
If, in a PROFINET system, you include the switch in the hardware configuration of the controller, the
appropriate address settings are automatically carried out via the controller afterwards.
