Write Modbus Application
Software packages that support Modbus protocol could be used to write Modbus
application for the XVG/eXVG. The necessary Modbus functions are Read
Registers, Write Single Register, and Write Multiple Registers.
-
All XVG/eXVG Modbus parameters are readable using Read Register
function.
-
Write to the writeable registers can be accomplished with Write functions and
appropriate password.
User Responsibility
By using the Modbus read and write functions, it is possible to access all of the
XVG/eXVG parameters, features, and functions. The following precautions must
be considered when writing your own Modbus application:
