7.7.35 Comm 2 Data Format
A read returns the Comm 2 data format of the FL3102. A write changes the data
format to the requested data format. After the data format has been changed to
the addressed unit, the MODBUS communications may cease or start producing
Comm errors because the data format has changed. Therefore, the master will
have to change its data format to the slave’s new data format in order to restart
or provide proper communications.
