57, 61, 62, 64, 67 to 69, 81 received token)
to 96, 98, 100 83: BACnet valid APDU counter (Displays the count of
valid APDU detection)
84: BACnet communication error counter (Displays the
count of communication error)

The count of the setting values "82" and "83" returns to
"0" if the count exceeds "9999". The upper limit of the
count of the setting value "84" is "9999".

When the figure obtained by combining the Pr.728 and
(0 to 418)
Pr.729 settings is not within "0 to 4194302", the setting
is out of range.
When Pr.728 = "419", the setting range of Pr.729 is "0
0 to 9999
to 4302".
(0 to 4302)
When Pr.729 = "4303" or more, the setting range of
Pr.728 is "0 to 418".
