Hello Braylen , 

Please check profibus wire , if it is damaged or cut.

Check the continuity of current with multi meter for cable. That will show if the cable is okay.

Here is the method.

Next check the connector pins and circuit.  Make sure they are not damaged.

Here is the link of connecting profibus cable with siemens connector.

If necessary change the cable and connector.

I hope it will be helpful.
