Default: 3
The application buffers (ai, ao, and aop) all have a range of 1 to 100 for the
allowable number of buffers.
You can set priority buffers to a count of 0 (zero), but you must specify at least
one non-priority buffer in both directions (input and output). However,

devices to have at
least one priority buffer. Eliminating priority buffers will prevent certification.
The LonTalk Interface Developer utility issues messages that relate to the buffer
configuration. For example, the utility issues messages for the following
situations:
• If the configuration exceeds the available buffer space, the utility issues
error LID#62 (Insufficient buffer space).
• If additional netin or netout buffers of the currently configured size could
be added to the configuration, the utility issues warning LID#4026
(Unused buffer space).
• If at least one 20-byte buffer could be added to the configuration, the
utility issues hint LID#8005 (Unused buffer space).
