2. If no device errors occurred:

l If tag is a block tag, the entire block will be invalidated. All tags within that block will be invalidated.

l If tag is an array tag or string tag, just this tag will be invalidated.

Possible Cause:

An error was returned from the PLC or NetLink adapter.

Solution:

1. If the error code=0x11, an incorrect MPI ID may be set. Determine the MPI ID through which

communications are occurring, and then re-enter it in the MPI ID Device Property field.

2. If the error code=0x87, users may be accessing data out of range in the device. Verify the device's

address limits, and then correct the tag references causing the error.

3. For all other errors, contact Technical Support.

Error Codes

Unable to write to <address> on device <device name>. Device not

responding.

Error Type:

Warning

Result:

The write operation to the address failed.

Possible Cause:

1. The connection between the device and the host PC is broken.

2. The named device may have been assigned an incorrect IP address.

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

Solution:

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

2. Verify the IP address given to the named device matches that of the actual device.

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".

Unable to write to <address> on device <device name>. Device returned data

access error [Code=<code>].

Error Type:

Warning

Result:

The write operation to the address failed.

Possible Cause:

A data access error occurred. This will occur if, for instance, a requested address is out of range or is being

referenced incorrectly.

Solution:

Contact Technical Support.
