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.).
