TD ADDENDUM
SECTION 1.
FUNCTIONAL MODES
AD-1-6
The *D15 entries are sent when the program is
retrieved.
They can also be set like other *D
settings via the DLD file.
1.8.9 ALLOCATE MEMORY FOR GENERAL
PURPOSE FILES
*D16:xx
;allocate xx 64K byte chunks of
memory for general purpose files.
The area comes out of final storage
space.
Files are stored in a circular
buffer (ring memory) in this space.

information. This is view only.

1.8.12
PAKBUS NEIGHBOR FILTER
In some networks, sending beacons can be
disruptive.
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
send “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
compiling 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.
