"0-BASED" OR "1-BASED” MODBUS ADDRESSES
According to the Modbus standard the Holding Register registers are addressable from 0 to 65535, there are 2
different conventions for numbering the addresses: "0-BASED" and "1-BASED".
For greater clarity, Seneca shows its register tables in both conventions.
