How to Fix the "Modbus Poll Bytes Missing" Error: A Complete Guide
Don't poll too fast. If your scan rate is 100ms but the device takes 200ms to respond, the packets will collide. 6. Eliminate EMI (Electromagnetic Interference)
Increase this from the default (usually 1000ms) to 3000ms to see if the error clears.
