For Modbus communication, many function codes (e.g., Read Holding Registers, Function Code 03) are inherently 16-bit. When using a ProSoft or Rockwell AOI (Add-On Instruction) for Modbus, the data is often buffered into an array of INT[100] . The programmer must then recombine two consecutive 16-bit INT s into a single 32-bit DINT for floating-point or high-precision integer values using a combination of MUL and ADD or the JSR instruction for custom logic.

New users often ask: “If the Logix processor is 32-bit, why not always use DINT?” The answer lies in and CIP messaging . The Story of "The Smarter Conveyor" For Modbus
She went to work. Whoops —she clicked the icon. The software churned, establishing a serial connection to the PLC. The project tree populated: Tasks, Programs, Tags. But the controller status bar was red.
