Why is the NET LED on my CREVIS Adapter red?
A red NET LED on your CREVIS Adapter indicates a communication connection has been lost. Check the BUS line cable for connection with the master. Also, check for a duplicate address.
What to do if I/O LED flashes red on CREVIS Adapter?
If the I/O LED on your CREVIS Adapter flashes red, there may be a failure in the configuration baud rate, a failure of initialization I/O, or the NA series may notice an unidentified expansion module ID. Check the communication cable with the master and the power for the master. Also, use an expansion slot of up to 32 and compose the IO total size so that it is not excessive. Finally, check the status of the expansion module.
How to fix NET LED when it turns off on CREVIS Adapter?
If the NET LED turns off, it indicates a failure of communication with the Master. Check the main power for the master and the communication cable.
