folder in the temporary directory.

TFTP -i rma-1894854 PUT %TEMP%\TFTP\ModbusTcp.csv nor:\Gateway\ModbusTcp.csv
SNTP Client
Setup keys: SntpAddress
The RMA PLUS implements a Simple Network Time Protocol (SNTP) client. If the configuration key
SntpAddress is present, the RMA PLUS will attempt to synchronize its time with the configured SNTP
server once per day. If the connection fails, the RMA PLUS will try again at a faster interval until the
connection is successful.
Wireshark
Wireshark is an Ethernet network analyzer. If you are trying to diagnose an Ethernet issue, Wireshark is
an invaluable tool. The factory may ask for a network capture to help diagnose problems.
If the problem is between PC software and the RMA PLUS, you can install Wireshark on the PC with no
additional configuration. If the problem is between a device without Wireshark and the RMA PLUS, you
can activate the port mirroring feature of the embedded switch to obtain a network capture.
Watbus
Watbus is a RS-485 token-passing network that may contain both masters and slaves. It is a proprietary
protocol that all products implement. There are two varieties
– high-speed and low-speed. The RMA
PLUS is a master on both channels.
The logical address is independently software selectable for each bus. Use Standard Bus Instance 1 to
change the logical address for low-speed Watbus. Use Standard Bus Instance 2 to change the logical
address for high-speed Watbus.
See Standard Bus for member documentation.
Address Segmentation
The legacy bus (low-speed Watbus) is segmented and thus requires an additional configuration
parameter to address data points. Therefore, when you purchase an EZ-ZONE RUI and EZ-ZONE PM, and
