I have seen this happen on one of my cRIO's. I had disabled the distributed clock on the etherCAT chassis and forgot about it until
diagnosing a problem with digital output no longer working in the extended chassis. After renenabling the distributed clock the digital I/O started working correctly.
Has anyone else seen this problem? I was under the impression that this distributed clock only proved hard frame sync to the extend chassis and all I/O should work
without it.
