Hello, 2 wire means power supply and signal in the same 2 wire, 4 wire means 2 wire only for signal and power supply from other connection. In your case you have to put 4 wire in hardware configuration. Your analog input board also have range module. Please check if you have correct wiring and correct module position at pag.372-373 of this manual.
