Writeable?
Type
Modbus address * 256 + 6. For example an
N N EC-F9 at Modbus address 003 will appear as
774 or 0x0306.
C N analog_value (2)
C N normal (0)
"EC-F9 GGGG AdXXX.Cmin" where GGGG is
N N the gas name and XXX is the Modbus
address. The gas name is often "NH3".
C N FALSE
Gas threshold. Synchronization is
maintained with the 301C and the EC-F9.
N Y
Whichever value is written last is
distributed to the other two locations.
C N no_fault_detected (0)
C N always false (0)
C N always false (0)
C N always false (0)
C N always false (0)
C N Usually ppm (96)
Modbus address * 256 + 7. For example an
N N EC-F9 at Modbus address 003 will appear as
775 or 0x0307.
C N analog_value (2)
C N normal (0)
"EC-F9 GGGG AdXXX.Cmax" where GGGG is
N N the gas name and XXX is the Modbus
address. The gas name is often "NH3".
C N FALSE
Gas threshold. Synchronization is
maintained with the 301C and the EC-F9.
N Y
Whichever value is written last is
distributed to the other two locations.
C N no_fault_detected (0)
C N always false (0)
