I found many new properties in BACnet that were not decoded correctly in
Wireshark. I have attached a patch that adds decoding to the following
properties:
Fixed the following properties to decode:
In the Accumulator Object:
scale (187)
prescale (185)
logging-record (184)
In Access Door Object:
door-members (228)
masked-alarm-values (234)
In the Pulse Converter Object:
input-reference (181)
In the Group Object:
list-of-group-members (53)
In the Event Enrollment Object:
object-property-reference (78)
In the Command Object:
action (2)
In the Trend Log Multiple object:
log-buffer (131)
In the Event Log Object:
log-buffer (131)
In the Structured View object:
subordinate-list (211)
Added decoding for the following enumeration type properties:
Logging-type (197)
event-state (36)
reliability (103)
notify-type (208)
door-status (231)
lock-status (233)
secured-status (235)
maintenance-required (158)
program-state (92)
program-change (90)
reason-for-halt (100)
mode (160)
silenced (163)
operation-expected (161)
tracking-value (164)
file-access-method (41)
The above fixes also fixed the log-buffer decoding of the old trend log
recorded as Wireshark bug: #6458
I believe this patch also fixes bug: #6235. But the original bug did not
contain a capture file so I am not positive my capture represents the
originators issue.
