What are my best option if I want to aggregate some , faster than a minute, sampled modbus data and send off min/max/avg to the cloud every minute?
The best option would be to use the Flexy 205. WIth the Flexy it allows you to develop some Basic IDE/ and Java API coding to calculate the data, then send it to where you need too.
I would reach out to our sales department so that they can assist with providing the right solution for you.
