interrupted by removing the fieldbus cable.

Plug the end module in the middle of the

node. Switch the coupler off and on again.

If the I/O LED keeps blinking, displace the

end module anew. If there is only one

module left which is connected to the

coupler and if the I/O LED lights up, either

the module or the coupler is defective.

Change the defective component.
