Why different buses

and solutions

• RS422-RS485 communication in a local network:

all the measurements made by single instruments

can be gathered through a standard Modbus to a

PLC or a PC in order to carry out specific

variable analysis and control (Wattsoft).

• Modem/RS232 communication: if the

measuring devices are spread in a wide

area or in different countries with the need

to collect the local data for centralised

analysis, the right answer is WM4 or

PQT90 with external modem together with

Wm4Soft or PqtSoft software.

• Wireless communication: if the high

distances or specific applications are not

allowing to use ordinary wired systems, the

solution is called PqtKit with PqtSoft. A

GSM/GPRS communication kit with a proper

powerful network data download software.

• Ethernet and Internet communication:

if it is needed to measure the variables

exploiting the existing LAN, the solution is

WM4 or PQT90 with AR1060 plug-in module.

It easily displays the variables, the consumptions

and the trends in any enabled PC of the LAN.

Moreover, using the WEB server capability of

AR1060, the same data can be shown outside the

company.

• Dupline communication: if the load consumptions

and alarms have to be monitored together with a

powerful building automation system, the unique

solution is called Carlo Gavazzi Dupline installation bus.

Everything under control using only one bus system.
