All Opto 22 products are designed, manufactured, and supported in the U.S.A. from our Temecula, California headquarters and factory
Emphasis on Quality
Opto 22 I/O, controllers, and SSRs are famous for their quality and reliability. Customers often comment about their dusty, 40-year-old "Optos" still doing the job in the back of a factory somewhere. With this kind of reliability, we can afford to guarantee SSRs and most I/O modules for life.
Made and Supported in the U.S.A.
Since all our products are manufactured and individually tested at our headquarters in Temecula, California, we control quality from the ground up. So we also give you FREE pre-sales engineering help, free hands-on training, and free product support from experienced engineers.
Making Automation Simple
Because we're engineers, we know what it's like to lose an idea because it's too hard to implement. Designing and integrating automation systems can be frustrating. We simplify your job with open standards, easy-to-use software, clear documents, and how-to videos.

Glad you enjoyed it

I do not see the MQTT Engine tab. Was this configured?

[@sergio2801]

do you have information on how you set up or where you got the certificate file for the secure connection?

[@cchannel1430]

would like to know that too

[@svarodzic]

Nice intro. Thanks. The only thing is missing, imho, is the security aspect. Is there any way to authenticate a client (I hope you realize that username/password is not a secure way of doing it or TLS is not a bullet proves either) then also what about permissions for publichers and subscribers, otherwise how would you prevent DDoS attacs or someone getting the data that it not supposed to get, and the things like this.

So where does those tags come from though? You've been creating the tags in the PLC before right ?

[@cchannel1430]

yes

Would I need Chariot MQTT Server or can I use ActiveMQ instead?

[@Opto22]

Any 3.1.1 compliant MQTT broker/server will work!
