1.3.4 RO String
Read only access to string types.
Each AquaMaster 3 String type requires 18 MODBUS Registers (36 bytes). Consequently, RO String
Register addresses are assigned at intervals of 18 and the Request Message must provide Quantity of
Inputs in multiples of 18.
Read Input Registers 2271 to 2288
