ETCio 100 and Ethercat

We have one of the ETCio 100 modules connected to Twincat 2. I’m able to read and write the I/O in Free/Config Mode. But when I try to go in to Run Mode, I am unable to get the device to go pass Pre-Op Mode.

Any assistance would be greatly appreciated.


I figured it out. I had linked my variables to some PLC inputs/outputs and of course the PLC wasn’t running, thus no synchronization between the two.
