Corrective Action: Significance:
14 Block transfer queue full. The VME master processor
issued a block transfer command when the scanner's
block transfer queue was full.

the command.
15 Invalid length of data. The VME master processor
specified a length that cannot be used for the
command issued.
Specify a proper length.

issued a:
• SCAN LIST command that deletes an adapter listed
in a FAULT DEPENDENT GROUP.
• command placing an adapter not in the scan list into
a FAULT DEPENDENT GROUP.
1. Adjust the fault dependent group and then reĆissue
the scan list.
2. Adjust the scan list and the reĆissue the fault
dependent group command.
23 Block transfer timeout. A block transfer specified by

I/O link error. A failure occurred in the transfer of
information between the I/O module and the scanner.
An application program cannot cause these errors,
because they are associated with the communication
protocol on the I/O link.
1. Check the block transfer hardware configuration.
2. Eliminate electrical noise that may interfere with
remote I/O communication.
3. Use 57.6 kbps instead of 115.2 kpbs.
4. Ensure proper grounding of your I/O racks.
5. Consult the factory and/or replace the block
transfer module.
6. An error occurred within the scanner. Try cycling
power before removing the scanner.
