6. BFM
The module USES Modbus to exchange temperature data and other
information with the main module through BFM. A cache of read and
write attributes can be read and written using the MODBUS directive.
MODBUS supports 01, 03, 05, 06 and 16 functions. 01, 05 function
code to the bit register operation, 03, 06, 16 function code to the
integer register operation, if read reserved unit, will get 0 value. With
MODBUS protocol, up to 100 BFM units can be read and written at one
time.
Note: MTCW series thermostat support MTC series thermostat BFM
area.
