Hi,
Error 33612 can be caused for the reasons you have listed. One scenario is that your setup might be correct but the connection just times out because it does not receive a response from the modules.
This knowledgebase explains this scenario in more detail and the solution to avoid this error.
The second post on
this discussion forum are also more troubleshooting tips for you.
A few questions:
1. Are you connected using a crossover cable or a straight through cable?
2. Have you always had this problem?
3. Are you able to ping to the controllers/Ethernet modules address?
Answering the above questions along with answering RavenFans questions will help us to help you.
Thanks!
Warm regards,
