RS-485 Modbus to Host
The Modbus Register assignment as available to the Modbus Master Host communicating with the FM on
serial channel 2 is given in this section.
The first 64 registers provide the state of each Mod10 SSC module’s concentration reading and status. The
Host can get the whole group of data from one poll of the FM by getting these registers 40000 through 40063.
