Use Data Type Floats
The Gateway’s Modbus Register Remapping provides an option to remap all registers
to 32-bit floats. This allows the user to enter a register and its data type knowing that
it will be read from the gateway via Modbus as two 16-bit registers.
To use the floating-point remapping, select the ‘Use Data Type Float’ check box in the
lower right of the remap window. This will erase the current register remap in the
Gateway; the user
will be asked to confirm this action before proceeding.
For each even numbered register address in the remap table, enter the Modbus ID, Register Address,
and select the data type. The data types are provided in a pull-down list. Click the ‘
Write to GW’ button
to remap the register(s).
The

fields will automatically be filled in by the gateway
once the mapping is written to the gateway.
