REPORT SLAVE ID FUNCTION CODE
The MODBUS implementation of the ELECTRA-flo supports
the use of function code 17, Report Slave ID.
When a message is sent to the meter requesting the slave ID,
the following information is returned:
ELECTRA-flo G5
The meter will report data in decimal or HEX, depending on
the control system settings. The data must be converted from
decimal/HEX to ASCII in order to form the string.
