Then there must be something terrible wrong with the wiring of the port or the level of the signals is to high. Attached the pin assignment of the S7-200 communication port, notice that there is 24V on the same connector, maybe you shortwire these pins.

Okay. Do you have any ideas of what it could be? Is it related to the communication port? |

Hello, I could be a problem in the internal power supply, on the comunication connector there is 24V to power i.e. a TD, see attachment. So try to follow that pins to your resistor and measure the sensor powersupply on the CPU (located on the left side of the input terminals.
