What or cable connects your PC to the slave device?
Modbus Poll waits for a response based on a user-defined timeout clock. If a slave device processes data slowly, it might start sending the response late. If the timeout limit hits mid-packet, Modbus Poll drops the connection and reports missing bytes. 3. Inter-Character Delay Violations modbus poll bytes missing error fixed
Modbus RTU is extremely sensitive to serial configuration mismatches. If the baud rate matches but the parity or stop bits do not, the master will receive "garbage" bytes, calculate that the frame is invalid, and report missing bytes. What or cable connects your PC to the slave device
Set this to None unless your hardware specifically requires RTS/CTS or DTR/DSR. Step 2: Optimize Timing and Timeout Parameters the master will receive "garbage" bytes
