Mode Description
Monitor DevId Device ID at
Address
X Device ID when an I-Am is seen in
a capture (trigger with Who-Is) or
-1 if not seen.
Monitor RxTkn Tokens Received
by Address
X Displays the number of Token
Frames the device receives. In
MS/TP, each master device passes
a logical token to the next device
during normal operation. Only the
master device currently holding
the token is allowed to initiate a
message; thus, the number of
Token Frames sent or received is
large. Normally the number of
Token Frames received should be
almost the same as the number of
Token Frames transmitted.
Monitor PFM Poll For Master
by Address
X Displays the number of PFM
frames sent by the device. In
normal operation on a clean
network, only the bus supervisor
(MAC address 0) and the highest
numbered master device on the
network is sending PFM frames.
These frames are used to discover
other devices on the network.
Monitor RPM Reply To PFM by
Address
X Counts the number of Reply to
PFM frames the device transmits.
On a clean network during normal
operation, only one Reply to PFM
frame needs to be sent when the
device first comes online. These
frames are used to announce the
presence of other devices on the
network.
