7.7.8 Options
A read returns the status of the settings for the Detector Sensitivity, Relay Delay, Relay
Latching/Non-Latching and Relay Energized/Non-Energized features from EEPROM. A
write command changes the settings for the EEPROM.
Exception: If an EEPROM write error occurs, then the Exception Code 04 (Slave Device
Failure) is returned.
These Functions operate on the Low Data Byte.

7.7.9 Address
A read returns the address of the FL3112. A write changes the address to the requested
address. The range of the address is 1 to 247 (01 to F7 Hex). After the address has been
changed to the slave unit, the Modbus communications will cease because the address
has changed; therefore the master will have to change its query address to the slave’s new
address in order to restart the communications.
Exception: If an EEPROM write error occurs, then the Exception Code 04 (Slave Device
Failure) is returned.
