The term Index in the Repeating block addresses used in the above table refers to a
calculation of
Index = Stack Index * Length of Repeating block
. By definition, the 803
Repeating block is 16 Modbus registers in length.
9.1.5. Accessing MESA Models
MESA models are located contiguously in the Modbus address space starting at a base address of
40000
. The Common Model is always located first in this space. The End Model is always last and is
used to denote the end of MESA Modbus registers. Each model located between the Common Model
and the End Model has a numeric identifier as well as a length. A handy tool that can be used to
explore the MESA Modbus registers for Nuvation Energy BMS is
modpoll.exe
. It is available for free
download at http://www.modbusdriver.com/modpoll.html .
Using
modpoll.exe
, the Common Model can be polled from a using the following command (assuming
the device has an IP address of
192.168.1.21
)
