Adjusting message buffers in a Neuron chip

This procedure configures message buffer counts and sizes in the Neuron chip of a Local Lon Device.
Prerequisites: The kitLon palette is open.
 CAUTION: Do not change message buffer counts and sizes unless you fully understand the implications. An improper configuration can significantly degrade operation and/or result in loss of data. 
Perform the following steps:
  1. Drag or copy the BufferParams component to your Local Lon Device in the Nav tree.
  2. Double-click the BufferParams component and take a screen capture or otherwise record the default buffer properties.
  3. To verify the Neuron’s current buffer configuration, right-click the Lon network node in the Nav tree, click Views > Lon Utilities Manager, configure Command: Data Structs, Subcommand: Read Only Structure, and click Execute.
  4. Double-click BufferParams and configure a different set of message buffers.
    The component’s Current Size property reflects the changes to buffer count or size. To be applicable, modifications cannot exceed the size shown in the Original Size property—that is, Current Size must be less than or equal to Original Size. For example, to increase a buffer size, you may need to decrease its count.

    The system does not automatically write message buffer changes saved on the BufferParam’s Property Sheet to the Neuron chip in the Local Lon Device.

  5. Before continuing, ensure that Current Size less than or equal to Original Size, and click Save.
  6. To write the message buffer changes to the Neuron chip, right-click the BufferParams node in the Nav tree and click Actions > Update Buffers.
    If Current Size is greater than Original Size, the job throws an exception, and writes no changes to the Neuron chip.
