ModbusOption (Modbus Option)

An optional parameter that is used to specify the data type of the Modbus variables.

Code Description
0 or absent Default; 32-bit float or Long, the standard ordering of the 2 byte registers are reversed (CDAB).
1 If the Modbus variable array is defined as a Long, variables are treated as 16-bit signed integers.
2 If the Modbus variable array is defined as a 32-bit float or a Long, with no reversal of the byte order (ABCD).
3 If the Modbus variable array is defined as a Long, variables are treated as 16-bit unsigned integers.
10 Modbus ASCII, 4 bytes, CDAB.
11 Modbus ASCII, 2 bytes, signed.
12 Modbus ASCII, 4 bytes, ABCD.
13 Modbus ASCII, 2 bytes, unsigned.
