Unable to write to <address> on device <device name>. Frame contains

errors.

Error Type:

Warning

Result:

The write operation to the address failed.

Possible Cause:

1. The TPDU response size is incorrect.

2. An unexpected frame was received. The response code may be incorrect.

3. The frame sequence is out of order.

4. The device's CPU work load is too high.

Solution:

1. Cable noise may cause distortion in the frame, resulting in erroneous data. It may also cause dropped

frames. Verify the cabling between the PC and the PLC's device.

2. Reduce network traffic. If this error occurs frequently, increase the Request Timeout and/or Fail After

attempt count.

3. If this error occurs frequently, decrease the tag group scan rate to reduce the work load on the PLC's CPU.

4. Increase the "Scan Cycle Load from Communication" and "Scan Cycle Monitoring Time".
