 Data Address (PARAM14 and PARAM15)
These parameters give the data address that was requested by the remote station.
For function codes 01 to 10 hex, the requested address is the word size address indicated only by
PARAM14. If the function code is 43 hex, the requested address is the long-word size address given
by PARAM14 and PARAM15.
*1. Coil or input relay read/write requests: Enter the address of the first bit of the data.
*2. Continuous register read/write requests: Enter the address of the first word of the data.
*3. Non-consecutive register read/write requests: Enter the address of the first M register of the address table.
