To illustrate data communication, an example frame containing a measured volume of
876543 liters will be used. Based on the settings applied to the first module, to send a
frame the fields to be sent to the serial port are C-Field and CI-Field, plus an optional
Data-Field. In this example, a C-Field value of 0x44 (SEND / NO REPLY) and a CI-
Field value of 0x78 (indicating a frame from a meter to a data concentrator, without

hexadecimal notation) 0B 13 43 65 87, indicating a value of 876543 liters expressed
