Suggestions
CAN bus BUS OFF or sending/receiving error counter exceed alarm val-
ue.
Check whether CAN baud rate of gateway is the same as in other nodes
on CAN network.
Need a terminal resistance on CAN network or the gateway has no con-
nection to CAN network.
Need a terminal resistance on CAN network or the node connected with
gateway fail.
There is error frame form CAN network, but does not affect communica-
tion.
Check the baud rate of all the nodes on the CAN network. If they are all
the same, change a lower baud rate and try again.
Modbus slave address on Modbus network is not the same with the
gateway ready to read
Modbus slave device on Modbus network does not support the function
code configured in the gateway
