Detailed Description

A type for 80 registers respectively 40 values of 32 bit.

Modbus RS484 (aka Modbus/RTU; RTU = Remote Terminal Unit) has a very restricted maximum telegram length of 256, allowing for 252 data bytes, respectively 248 value bytes or 124 registers in say FC4 (read input registers); see sdm124regs_t. EASTRON smart meters restrict this further to 80 registers respectively a maximum of 40 float values, called parameters.
