1794-anet

I have 1794-ANET Module.
Network Light is blinking.
Everything is ok. Online and data is passing.
I/O try has no errors.

Any clues to what it could be?

Is the Network Status LED blinking green or blinking red ?

Are there any connection timeouts indicated for the adapter in Studio 5000 ? An analog module timeout would cause a flashing red Network Status indicator while allowing the discrete I/O to work correctly.

Are you SURE you are looking at the correct device ? Watch its status in Studio 5000 when you disconnect it from the network to be absolutely certain you are looking at the device you think you are looking at.
