ModBus on SL/HL/W - Mislabelling?

Both are correct Smile
Numbering in your doc refers to "traditional numbering standard", while RTU read test uses Modbus function number. For some historical reason address numbering and function numbers for registers are swapped. Keep in mind that actual registers are numbered from 0, not from 1 as specified in your doc.
