Float Start
0 to 65535
This parameter defines the first register of floating-point data. All requests with
register values greater-than or equal to this value will be considered floating-point
data requests. This parameter is only used if the Float Flag is enabled. For
example, if a value of 7000 is entered, all requests for registers 7000 and above
will be considered as floating-point data.
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.
Output Offset
This parameter defines the start register for the Modbus command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Output Offset value is set to 3000, data requests for Modbus
Coil Register address 00001, will use the internal database register 3000, bit 0. If
the Output Offset value is set to 3000, data requires for Modbus Coil register
address 00016 will use the internal database register 3000, bit 15. Function
codes affected are 1, 5, and 15.
Bit Input Offset
0 to 3999
This parameter defines the start register for Modbus command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Bit Input Offset value is set to 3000, data requests for Modbus
Input Register address 10001 will use the internal database register 3000, bit 0. If
the Bit Input Offset is set to 3000, data requests for Modbus Coil register address
10016 will use the internal database register 3000, bit 15. Function code 2 is
affected.
Holding Register Offset
0 to 4999
This parameter defines the start register for the Modbus Command data in the
internal database. This parameter is enabled when a value greater than 0 is set.
For example, if the Holding Register Offset value is set to 4000, data requests for
Modbus Word register 40001 will use the internal database register 4000.
Function codes affected are 3, 6, 16, & 23.
