Description
Suggestions
1
PBF (PROFIBUS DP Failure) always read
PROFIBUS DP connection fail
2
PBF (PROFIBUS DP Failure) read out
PROFIBUS DP connection OK
3
CAN-STATUS read light on in run status
CAN BUS OFF or error counter beyond alert
value;
Check CAN baudrate of gateway, and the
baudrate must be the same with other nodes
of CAN network
4
CAN-STATUS read light blinking in run status
Need a terminal resistance
1
on CAN network
or there is no connection between gateway
with CAN network
5
CAN-STATUS green light on but CAN transmit and
receive data fail in run status
Need a terminal resistance
1
on CAN network
or the node connected with gateway fail
6
CAN-STATUS read light blinking in run status
occasionally
There is error frame form CAN network, will
not affect communication
7
CAN-STATUS read light always blinking in run
status and no data in PROFIBUS DP
Check the baudrate of all the nodes on the
CAN network; If they are all the same, please
change a low baudrate and try again
8
ERR and RUN lights blinking fast
Check PROFIBUS DP network
Note: Terminal resistance
1
When communication distance is long or communication baudrate is high, users need a terminal resistance
(120Ω/2W) in both terminals of communication lines.
