Value
object_identifier R N N
Modbus address * 256 + 2. For example an
E3Point at Modbus address 000 will appear
as 2306 or 0x0902.
object_type enumerated R C N analog_value (2)
event_state enumerated R C N normal (0)
object_name character string R N N
"E3POINT GGGG AdXXX.Amin" where
GGGG is the gas name and XXX is the
Modbus address. Values for gas name
include "CO" and "COMB".
out_of_service boolean R C N FALSE
present_value real R N Y
Gas threshold less hysterisis.
Synchronization is maintained with the
301C and the E3Point. Whichever value is
written last is distributed to the other two
locations.
reliability enumerated O C N no_fault_detected (0)
status_flags
in_alarm boolean R C N always false (0)
fault boolean R C N always false (0)
overridden boolean R C N always false (0)
out_of_service boolean R C N always false (0)
units enumerated R C N ppm (96) or % (98)
object_identifier R N N
Modbus address * 256 + 3. For example an
E3Point at Modbus address 009 will appear
as 2307 or 0x0903.
object_type enumerated R C N analog_value (2)
event_state enumerated R C N normal (0)
object_name character string R N N
"E3POINT GGGG AdXXX.Amax" where
GGGG is the gas name and XXX is the
Modbus address. Values for gas name
include "CO" and "COMB".
out_of_service boolean R C N FALSE
present_value real R N Y
Gas threshold. Synchronization is
maintained with the 301C and the E3Point.
Whichever value is written last is
distributed to the other two locations.

out_of_service boolean R C N always false (0)
units enumerated R C N ppm (96) or % (98)
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.
