Data Logger Configuration For Scada Or Other Monitoring Systems; Set A Static Ip Address For The Data Logger; Configure The Serial Interfaces - ABB VSN700 Product Manual

Data logger configuration for SCADA or other monitoring
systems

Set a Static IP Address for the data logger

Connect a PC to the Eth1 port and browse to address
logger's web based configuration UI. In the Network tab configure a static IP address for the data
logger's Eth0 port that is either within the same subnet as the SCADA system or can be routed
to/from the SCADA system. Use a single space between your primary and secondary DNS
servers, if applicable. Alternatively, the data logger can be set for DHCP if the DHCP server that it
receives its IP address from is configured to always assign the same IP address to the data logger.

Configure the serial interfaces

Configure the serial port interfaces for the appropriate communication protocols based on the
devices installed at the site. If using legacy Power-One inverters that only communicate using the
Aurora protocol, then the serial interface they are connected to must be changed to Power-One
SunSpec Adapter for the inverter's data to be accessible by Modbus TCP clients. Note that the
Ultra® central inverter is only supported via Modbus RTU or via the Power-One SunSpec
Adapter options; it is not supported via the Aurora Protocol option. Setting the interface for
Modbus RTU will allow for better polling performance; however, advanced features like remote
inverter firmware upgrade are only available through the Power-One SunSpec Adapter option.
In the Home tab click the pencil icon
and Secondary RS-485 interfaces based on the type of devices connected to these ports. Polling
performance is better if half of the devices are connected to one of the data logger's RS-485 ports
and half connected to the other, though this may not be practical depending on the physical
locations of devices. Try to spread as many devices as possible across the two ports for better
polling performance. The protocols used on each interface can be changed on the Max version
data logger. They can both be set for the same protocol or different protocols. All devices daisy
chained to a particular port must use the same communication protocol and settings as those set in
the data logger for that port, including baud rate and parity checking. Note that to monitor the
Ultra® central inverter via Modbus RTU, the baud rate for the interface on the data logger must be
changed to 19,200 bps.
Verify that both ports are configured to the appropriate baud rate and parity for the connected serial
devices by clicking on the wrench icon
menu(s). If communicating with inverters via Modbus TCP, open the port(s) in the firewall
associated with the RS-485 interface(s) by clicking the wrench icon next to the red X to open the
