Maybe somebody can help me with this one!
I have to pick up an analog signal from a water level probe and send it through fiber optic (singlemode) some 4-5Km to a control station and get an analog signal again, process the signal and return ti back the same way. Can it be done with PLC, if possible, which PLCs can I use, I know I can only get ABB's and Moeller's (maybe Siemens) PLC's in my country!
All sugestions are welcome, I'm looking for any (any at all) possible solution.
