Hi @ all!
I have developed a photovoltaic charge controller. This charge controller should now learn to speak "modbus". So it can communicate with other devices (eg, with the monitoring modules for the individual battery cells). This communication works so far (RTU over RS485, charge controller is master or or a local PC is master and charge controller is slave).
Now we want to get the data of the charge controller and the connected slaves by PC via GPRS (And send configuration parameter) Thus it can work without any special sim card, the charge controller has to connect to the server (so far i know). How is it now possible from the PC to poll the charge controller? The Modbus master simulators (eg Modbus Poll) can only poll to a specific IP address, it does not opens open a socket, so the charge controller can connect to it. Is there any software that it can? Or is there a other way
I hope my description was understandable and sorry for my bad English.
greetings
