5. Remote monitoring (option: Wi-Fi, Ethernet, RS485, USB).
The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a monitoring
centre. Transmitting data concerning PSU status is possible due to an additional, external communication module
that is responsible for communication in Wi-Fi, Ethernet or RS485 standard. A USB-TTL interface enables
connection between the PSU and a computer.
In the further part of the chapter, there are presented different connection topologies which serve as examples
since more communication variations are possible. For more examples, study the manuals of particular interfaces.
5.1 Communication in the wi-fi wireless network.
The Wi-Fi wireless communication is to be implemented on the basis of additional interfaces: WI-Fi ‘INTW’
and RS485-WiFi operating within 2,4GHz frequency band, accordingly to the IDEE 802.11b standard.
The WiFi ‘INTW’ interface stall be mounted in a selected location inside the enclosure so that the serial
protrudes outwards.
Fig.19. WI-FI communication with the use of the WI-FI ”INTW” interface”.
The RS485-WiFi ‘INTRW’ interface is a device intended for converting signals between the RS485 bus and
the Wi-Fi network. To work correctly, the device requires external power supply within the range of 10÷30V DC e.g.
drawn from a PSU of the PSBEN series. The device is mounted in a hermetic enclosure that protects it against
adverse environmental conditions.
