Issue
When trying to set up X80 or Quantum EIO drops, cannot get a drop to come up and be recognized.

Product line
Modicon X80 IO, Modicon M580, Quantum EIO

Resolution
The above condition could indicate that the incorrect address is set on the switches. Power Down then try rotating each switch all the way around and back to 0 for the Tens and back to 1 (or the specific drop address) for the Ones.

If it does not recover after power up, this can also be caused be either the M580 not physically seeing the CRA (check cabling) or the incorrect CRA selected in the project configuration (there are multiple CRA choices (for X80 IO), make sure the configuration matches the hardware).

In the M580 Security settings, TFTP, EIP and DHCP / BOOTP need to be Enabled.

If in the Security settings you have activated Access Control, you will need to activate(select) TFTP and EIP in order to communicate to the CRA modules.

The CRA network should be isolated but another reason this might happen is if another module/device has the same IP address that the CRA module auto-assigns.
Something like an OPC module could have a default IP the same as the CRA was trying to have assigned based on drop rotary switch.
