ABB monitoring and communications
PVI-RS485-MODBUS Converter
PVI-RS485-MODBUS is the ABB
devices family able to convert
the proprietary Aurora Protocol
to ModBus RTU or ModBus TCP
communication protocol.
The PVI-RS485-MODBUS enables ABB
inverters to exchange data with thirdparty devices such as controller as well
as datalogger supporting ModBus (RTU
or TCP) communication protocol.
The PVI-RS485-MODBUS is a DIN rail
mounted device and can be configured
and upgraded locally by simply using
a PC (connected to the RS485 port
through ABB PVI-USB-RS232-485
Adapter) running a common testing
application able to operate as a
ModBus master for accessing data in
the PVI-RS485-MODBUS connected as
slave device.
The PVI-RS485-MODBUS is capable to
manage up to 32 ABB string inverters
or 32 ABB 55 kW inverter modules
and, according to the specific product
model, it allows customer to manage
inverter power control in range of Smart
Grid functionalities.
