Addressing
The analyzer's Modbus slave node address can be in the range of 0-250 with a
default of 1. All analyzers will respond to an address of 0, so this address can
be used to interrogate a single unit when its address is unknown or to
determine its address.
See Table 3–1 on page 3–15 for register definitions for both Gould and Daniel
Modbus modes. Be aware that for Gould Modbus the table follows the
convention of identifying the register with an offset of 40001. Therefore, the
actual value transmitted in the starting register field of the command is the
listed register value minus 40001, e.g., register 47001 is addressed as 7000.
