Allen-Bradley DH+ Driver Help

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

received contains errors

Error Type:

Warning

The Error Could Be:

1. Incorrect frame size received.

2. TNS mismatch.

3. Invalid response command returned from device.

Possible Cause:

1. Misalignment of packets due to connection/disconnection between PC and device.

2. There is bad cabling connecting the devices causing noise.

Solution:

The driver will recover from this error without intervention. If this error occurs frequently, there may be an issue

with the cabling or the device itself.

Unable to write to address '<address>' on device '<device name>'.

[STS=<value>, EXT STS=<value>]

Error Type:

Warning

Possible Cause:

The address written to does not exist in the PLC.

Solution:

1. Check the status and extended status codes that are being returned by the PLC. Note that an extended status

code may not always be returned and thus the error information is contained within the status code. The codes

are displayed in hexadecimal.

2. Status code errors in the low nibble of the status code indicate errors found by the local node. Errors found by

the local node occur when the card cannot see the destination PLC on the network for some reason.

3. Status code errors in the high nibble of the status code indicate errors found by the PLC. These errors are

generated when the data location is not available in the PLC or not writeable.
