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 .
Float Start 0 to 479 Defines the first register of floating-point data. All requests
with register values greater-than or equal to this value is
considered floating-point data requests. This parameter is
only used if the Float Flag is enabled. For example, if a value
of 200 is entered, all requests for registers 200 and above is
considered as floating-point data.
Float Offset 0 to 479 Defines the start register for floating-point data in the internal
database. This parameter is used only if the Float Flag is
enabled. For example, if the Float Offset value is set to 100
and the float start parameter is set to 200, data requests for
register 200 uses the internal Modbus register 100.
Output Offset 0 to 479 Specifies the offset address into the internal Modbus
database for network requests for Modbus function 1, 5 or 15
commands. For example, if the value is set to 100, an
address request of 0 corresponds to register 100 in the
database.
Bit Input Offset 0 to 479 Specifies the offset address into the internal Modbus
database for network requests for Modbus function 2
commands. For example, if the value is set to 150, an
address request of 0 returns the value at register 150 in the
database.
Holding Register
Offset 0 to 479 Specifies the offset address in the internal Modbus database
for network requests for Modbus function 3, 6, or 16
commands. For example, if a value of 250 is entered, a
request for address 0 corresponds to the register 250 in the
database.
Word Input
Offset 240 to 479 Specifies the offset address into the internal Modbus
database for network requests for Modbus function 4
commands. For example, if the value is set to 350, an
address request of 0 returns the value at register 350 in the
database.
Connection
Timeout 0 to 1200 Specifies the Server’s timeout period if it is not receiving any
new data in the amount of seconds preset.
