Modbus Poll Bytes Missing Error Fixed -

Add a delay in milliseconds to give the slave time to process.

Industrial environments are plagued by Electromagnetic Interference (EMI) from Variable Frequency Drives (VFDs), motors, and high-voltage lines. EMI can corrupt bytes mid-transit. When a byte is corrupted, the PC's UART serial controller may drop it entirely due to parity or framing errors, resulting in a missing byte count at the software layer. Verify your physical layer deployment: modbus poll bytes missing error fixed

Right-click your COM port in Device Manager and select . Go to Port Settings > Advanced . Change the Latency Timer (msec) from 16 down to 1 or 2 . To help troubleshoot your specific setup, tell me: Are you using Modbus RTU (Serial) or Modbus TCP (Ethernet) ? Add a delay in milliseconds to give the
