atvise Connect Modbus Sintaxis Options

The basic Items are

I = Digital Input

O = Coil

IR = Input Register

HR = Holding Register

1. To extract a BIT from an Register you can use this example:

       HRX2.1  = where "HRX" is the sintaxis for bits, "2" is the number of register you want to read and ".1" is the bit you want to read.

2.  To join 2 registers together to form 32 bit Integers or Real numbers.

   - As a 32 Bit Integer   HRDI1  where HRDI means Holding Register Double Integer and "1" is the register number

  - As a 32 Bit Float  HRF1 where HRF1 means Holding Register Float and "1" is the register number

  - As a 32 bit Word   HRDW1 where HRDW means  Holding Register Double Word and "1" is the register number 

If you want to work with 64 bit registers instead of the "D" letter for Double, you can use the letter "Q".

3. To configure the register as Signed or Unsigned

 - For 16 bit register

        - HRI1  = means HRI sets as signed and "1" is the register number.

         - HRW1 = means HRW sets as unsigned and "1" is the register number. 

4. For bit Swaping you can append the word "SWAP" at the end of any sintaxis.
