REGISTERS
The logger configurable parameters are organized in a Table of Registers. The block reading command makes possible to read
multiple registers with the same request.
The configuration software, however, makes such table not necessary, once it reads and writes in all registers that require
configuration. Each parameter in the table is a word of 16 bits.
The available Modbus command for the reading operation is the following:
