Convert DINT to 2 word

[Michael Ong 0]

Hi Sir,

I'm using NX1P2-9000 CPU, How can i convert DINT to 2 WORD?

Example:

input from HMI Data will 12345678, I need to export this DATA to SCADA. From PLC to SCADA using Modbus interface which is accept WORD or BYTE DATA. So how can i convert this DINT to 2 difference WORD then i can move to 2 difference modbus address.

 

Thanks

One option would be to use CopyNumToDWORD will convert it to DWORD, then you can use MoveDigit and move 4 digits starting at first to a word, then move 4 digits starting at 5th to another word...

As another option you can use ToAryByte to convert the DINT to an array of bytes.

Can your SCADA reassemble the data into a DINT once it receives it?

not sure i recall instruction set but this can be done on any platform using generic mask operations

Word_Low = MyDint AND 65535 ; AND with 0xFFFF to get the lower 16 bits

Word_High = MyDint \ 65536 ; integer division (or shift right 16 places) to get the higher 16 bits
