4.1.A.4.4 Description registers
Two description registers, A and B, are associated with each individual Modbus
measurement register (Table 5). The Modbus description registers allow third parties to
develop external devices that have plug and play capabilities with the FL900 logger and
minimize manual setup by the end user. Each description register can be queried by an
external device to get more details about the measurement value.
