No one can help you better than yourself ...
1 - Check well that the hardware configuration is correct.
2 - Check that the bus cable is connected properly and respect the polarity.
3 - Check the speed of communication that is set correctly for the module slave.
4 - Check the resistance in ohms at the end of the cable before the module sllave,maybe the cable is broken..!
Best Regards!
