I’m setting up a Cozy+ for the first time to talk to an Allen Bradley PLC. Is there a tech support phone number I can call rather that using a forum?
You should create a case at https://support.hms-networks.com for the quickest access to support.
I would encourage you to read the getting started documents and watching the videos here. Then if you run into a specific problem, please list the details of the problem in the case.
If you don’t want to read the documentation or watch the videos and just want someone to help you with the setup over the phone, we have a service for that. Please create a case and mention that you are interested in the startup service.
