Note:
1) Modicon 984 PLCs support remapping of both reads and writes.
2) In the MODBUS protocol, LONG data types default to a simplified implementation, with
a shortened range of 0 to 655,359,999. To increase the LONG data type to the full
range, set the [MODBUS]LongDataType parameter to either 1 or 3.
