Notes
1 -- 'R' indicates that this property is required by ASHRAE Standard 135
'O' indicates that the property is optional in ASHRAE Standard 135
2 -- 'C' indicates the property is hard-coded as a constant
'N' indicates the property is stored in non-volatile memory
'R' indicate the property is computed constantly and stored in RAM.

Writeable?
TxNumber * 256 + 1. The TxNumber is the
Modbus address plus the sensor number in
the 301EM. For example, sensor 2 on a
301EM at Modbus address 030 will appear
C N as 7937 or 0x1F01.
C N analog_input (0)
R N not meaningful
"VA301EM GGGG AdXXX .GGGG " where
GGGG is the gas name and XXX is the
Modbus address. Values for gas name
N N include "R11" and "NH3".
R N FALSE
R N Gas reading
As appropriate reports
no_fault_detected (0),
no_sensor (1), or
unreliable other (7)
R N Fault is detected within 60 seconds
R N not meaningful
if faulty "true" (1)
R N else "false" (0)
R N "false" (0)
R N "false" (0)
From 301EM, usually ppm (96)
N N
For Amin, TxNumber * 256 + 2,
For Amax, TxNumber * 256 + 3,
For Bmin, TxNumber * 256 + 4,
For Bmax, TxNumber * 256 + 5,
For Cmin, TxNumber * 256 + 6,
For Cmax, TxNumber * 256 + 7
The TxNumber is the Modbus address plus
N N the sensor number in the 301EM.
C N analog_value (2)
C N not meaningful.
"VA301EM GGGG AdXXX.LLLL" where GGGG
is the gas name, XXX is the
Modbus address plus the sensor number in
the 301EM and LLLL is a member of the set
{Amin, Amax, Bmin, Bmax, Cmin and
N N Cmax}.
C N FALSE
Writing alarm thresholds over BACnet not
N N supported.
C N not meaningful.
C N not meaningful.
C N not meaningful.
C N always false (0)
C N always false (0)
