Im looking for a Siemens' solution based on S7 300.
The task is to locate input / output modules about 1 KM away from where the central PLC cpu is located. Communication between the I/O modules and the PLC is to be effected via a wireless radio link.
Does Siemens have such a solution in place? If so, kindly suggest such a solution.
I need a total of approximately 30 inputs / 30 outputs in the field.
