Parameter Description
Device Count The number of MS/TP devices detected on the MS/TP bus. The
count does not include the CWCVT.
Devices A list of the MS/TP device addresses seen on the MS/TP bus.
Framing Errors A running count of the number of byte framing errors seen on
the MS/TP bus.
MS/TP Rx Bytes A running count of the number of received bytes on the MS/TP
bus.
APDU Rate Running count of all BACnet messages seen per minute from any
MS/TP device on the wired side.
Broadcast Rate Running count of the number of BACnet broadcast messages
received per minute from any MS/TP device on the wired side.
MS/TP → Wireless APDU Rate Running count of BACnet messages seen per minute from any
MS/TP device on the wired side to the host device on the wireless
side of the CWCVT.
MS/TP ← Wireless APDU Rate Running count of BACnet messages seen per minute from the
host device on the wireless side to any MS/TP device on the wired
side of the CWCVT.
Token Loop Time (ms) The amount of time in milliseconds for the MS/TP token to make
it around the token loop.
Dropped Tokens A running count of the number of times the CWCVT detects that
any device on the MS/TP bus fails to use and pass the token
causing the token to be recovered.
MS/TP Tx Failures A running counter of the number of times that an attempt to
transmit an MS/TP frame fails.
BIP Tx Failures A running counter of the number of times that an attempt to
transmit a BACnet frame over Wi-Fi fails.
Note: The values in this table do not update automatically. The values are updated when the
table is first viewed and when the Refresh button at the bottom of the table is pressed. These
values reset to 0 on every power cycle or when the Reset MS/TP Diagnostics button is pressed.
