What can I be doing wrong? I use 0x0A which is address 10. I try to use Modbus Poll, and Modbus scan to read the registers but the communications always fail (Same error). Unfortunately it always say that there is no communication (Timeout error). To read and modify register I’m using python and raspberry. ![]() ![]() I have modified ex_modbus_slave.c to do so. I only required to read and edit 2 registers (one is position and the other is inclination). I have already used RS485 to communicate thru serial without problem. Hi, I’m trying a simple Modbus communication using RS485. Please do not post bug Reports on this forum.
