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??
