Need a Modbus polling program using Modbus4J
We need a GLG API libary that is either "Java Servlet for JSP and JavaEE" or "Java Class Library for standalone or web deployment".
We simply want to poll 12 modbus registers for daq. From there our GLG Real-Time chart will display our results.
The polling will be RS-485.
From everything I've read, Modbus4J is the answer.
Anybody have something like this already made??
Mango can do this for you. There is a REST API where you can read and write to modbus registers.
Where can I get more info??
You can review our main site, then download the Mango files. Here is an article about exploring the API once you have Mango running on your machine: https://help.infiniteautomation.com/explore-the-api/
We need to update the document on API authentication which you'll need before you integrate your application but you can use Swagger to test all the end points and see the JSON formats
