16 commands (read and write Holding Registers) from a remote Client when it is

If the remote Client expects to receive or will send one complete 32-bit floating-
point value for each count of one (1), then set this parameter to Y
, the Server driver will return values from two consecutive 16-bit internal

memory registers (32 total bits) for each count in the read command, or receive
32-bits per count from the Client for write commands. Example: Count = 10,
Server driver will send 20 16-bit registers for 10 total 32-bit floating-point values.
If, however, the remote Client sends a count of two (2) for each 32-bit floating-
point value it expects to receive or send, or, if you do not plan to use floating-
point data in your application, then set this parameter to N
setting.
You will also need to set the Float Start and Float Offset parameters to
appropriate values whenever the Float Flag parameter is set to Y
