How to install an UWP 3.0 system
11
Different models and brands of energy meters can be mixed, and they can also have different baud rate
(see the
UWP 3.0 Tool
software manual for more details about how to configure the
UWP 3.0
to manage
them).
N.B. The energy meters should be configured and connected to the load as described in the
relevant instruction manuals. No configuration nor discovery can be carried out using the UWP
3.0 Tool software.
For more details about the wiring of the RS-485, please refer to appendix A.
1.1.3 BACnet
UWP 3.0 can work as a BACnet server, making available whatever set of variables to external BACnet
clients or BMS systems; please check the
UWP 3.0
tool manual for further details.
1.1.4 Modbus/TCP
1.1.4.1 Abstract
UWP 3.0
has an Ethernet port by which it is possible to connect both Modbus/TCP slaves and
Modbus/TCP masters at the same time.
1.1.4.2 UWP 3.0 as a Modbus/TCP Master
Any Modbus/TCP device can be connected to
UWP 3.0
, thanks to the MODBUS Editor Tool (MDE) a
software package part of the
UWP 3.0
Tool which allows to encapsulate any Modbus protocol into an
UWP 3.0
driver. It is also possible to send Modbus commands to a Modbus slave, thanks to the specific
feature of
UWP 3.0
.
1.1.4.3 UWP 3.0 as a Modbus/TCP Slave
The Ethernet port can also by set-up to work as a Modbus/TCP slave port. In this case, by using the
UWP
3.0
tool, it is possible to map the desired Modbus registers from the connected devices or functions to a
Modbus/TCP map.
Please check the
UWP 3.0
tool manual for further details.
