If, however, the remote server expects to use a count of two (2) for each 32-bit
floating-point value it sends or receives, 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 65535
Whenever the Float Flag parameter is set to Y
ES
, this parameter determines the
lowest Modbus Address, used in commands to a remote server, to consider as
commands to read or write floating-point data. All commands with address values
greater than or equal to this value will be considered floating-point data
commands. All commands with address values less than this value will be
considered normal 16-bit register data commands.
This parameter is used only if the Float Flag is set to Y
ES
. For example, if a value
of 7000 is entered, all commands sent with addresses of 47001 (or 407001) and
above will be considered as floating-point data commands and 32 bits of data will
be sent or received for each count of one in the command.
You will also need to set the Float Offset parameter to an appropriate value
whenever the Float Flag parameter is set to Y
ES
.
Float Offset
0 to 9999
This parameter 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 3000 and the Float Start parameter is set to
7000, data requests for register 7000 will use the internal Modbus register 3000.
ARP Timeout
1 to 60
This parameter specifies the number of seconds to wait for an ARP reply after a
request is issued.
Command Error Delay
0 to 300
This parameter specifies the number of 100 millisecond intervals to turn off a
command in the error list after an error is recognized for the command. If this
parameter is set to 0, there will be no delay.
