I would like to access a strategy variables without using the OPC server. Is optoMMP toolkit the way to go? From my reading of its documentation I would have to write the variables values from the Snap PAC S1 controller to one I/O brain Scratch Pad in order to be able to read them? There is no way to access a controller memory directly (modbus, or any other non OPC protocol)?
How does the OPC server access the controller data?
