Trends Error Rate Trend — Total number of errors within the interval time on this network,
including break errors, framing errors, etc..
Packet Rate Trend — BACnet/ARCNET data packets transmitted through router,
not the total utilization.
Port S1 Statistics
when used for MSTP
or
Port S2 Statistics
Error Counters UART Errors — UART receive and transmit errors such as break errors, framing
errors, parity errors, and overrun errors.
Invalid Frames — Received MS/TP frames that contain an error such as CRC.
Dropped Packets — Dropped receive and transmit frames. These may be dropped
due to buffer allocation failures, length errors, or APDU timeouts (in the case of
transmit frames)
Dropped Tokens — Dropped tokens that have been retransmitted.
No responses — Messages that did not receive a response from the destination
device.
Activity Counters BACnet/MSTP Rx Packets — BACnet/MSTP data packets received by the TV-
MPCXP.
BACnet/MSTP Tx Packets — BACnet/MSTP data packets transmitted by the TV-
MPCXP.
Latency Average Value (milliseconds) — The average time from when a packet is queued to
be transmitted until it is actually transmitted on the bus.
Maximum Value (milliseconds) — The maximum time from when a packet is
queued to be transmitted until it is actually transmitted on the bus
Trends Error Rate Trend — Total number of errors within the interval time on this network,
including break errors, framing errors, etc.
Packet Rate Trend — Percentage of total bus bandwidth used to transmit data
packets.
NOTE This is for all bus traffic, not just traffic generated by the TV-MPCXP.
