The *D15 entries are sent when the program is
retrieved. They can also be set like other *D
settings via the DLD file.

*D16:xx ;allocate xx 64K byte chunks of

The area comes out of final storage
space. Files are stored in a circular
buffer (ring memory) in this space.

*D17 allows viewing the current routing table

1.8.12 PAKBUS NEIGHBOR FILTER
In some networks, sending beacons can be
disr
uptive. Entering values in the *D19 mode
disables the beacon. A PakBus datalogger with
nonzero *D19 settings will not send beacons
and will only respond to beacons from nodes
with addresses in the neighbor list.
Instead of sending beacons, the datalogger will
s
end “
hello” messages to neighbors in the list to
determine if it can communicate with them.
Neighbors (or potential neighbors) should be
nodes that communicate directly with the
datalogger without going through a router.
Note that this list is not automatically cleared by
c
om
piling a new program. (It may be changed
if the new program contains *D19 entries.) It
can be edited by changing entries. Once 0 is
entered for a neighbor address, all entries
beyond the 0 entry are cleared.
