2.2.7 MNET Servers
This section contains database offset information used by the server when
accessed by external Clients. These offsets can be utilized to segment the
database by data type.
Float Flag
Y ES or N O
This flag specifies how the server driver will respond to Function Code 3, 6, and
16 commands (read and write Holding Registers) from a remote Client when it is
moving 32-bit floating-point data.
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
ES . When set to
Y ES , 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
O , which is the default
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
ES .
