Hi, 

I am using the AB7318-B for the purpose of translating CAN data from a pressure sensor for EV battery application to Ethernet/IP which is to be processed using  AB PLC.  

I have downloaded all the necessary supporting documents from the website, i was able to ping the module and the PLC is also able to see it, however, LED #5 keep flashing red  and the diagnostic report keep issuing ' Error Passive" as CAN State  while the Network State is " Offline".

My can node is terminated.

I ensured my of appropriate voltages for module and the CAN pressure sensor.

  Hi

  You do not say how the CAN consume transactions are configured - have you set up a single transaction to check for one CAN-ID or do you have multiple CAN-IDs in one consume transaction?

  Have you checked the log from the CAN Line Listener to be sure that the CAN-ID you expect is seen on the CAN bus?

  If you need detailed help then I suggest you open a support ticket so that you can share your configuration and logs with us.
