1 . In your message does not say that the functional blocks operate 
ONLY with the controllers NJ  of the family OMRON. 
My applications work with all families OMRON - CS1,CJ1,CJ2,NJ..., 
as well as with controllers from other manufacturers, for example Yaskawa. 
If you are an expert, you should know this when you write your comment.

2. If  company OMRON has developed MQTT functional blocks that, 
in my opinion, are not convenient, and do not fully solve the tasks 
of remote control, remote diagnostics, and collecting information 
about the object, then other developers do not have the right 
to develop similar software ??? 
My developments appeared in 2016, when these functional blocks OMRON
were not in sight.

3. Having extensive experience in implementing objects based on controllers,
 we know as well as specialists OMRON what users of equipment need for 
 IOT, remote diagnostics and monitoring
