We are looking for a polling program for the Modbus Protocol and Enron Modbus Protocol.  For both Protocols RTU and ASCII will need to be implemented as well as extended addressing.  I need one page to have constant polling for "live" data and another tab for settings that can read and write back to the controller.  For Enron modbus events, alarms and history will need to be implemented.  We need something like simplymodbus.ca but just for master serial to implement into our product.
