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 FI

LES

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

memor

y for general purpose files.

The area comes out of final storage

space. Files are stored in a circular

buffer (ring memory) in this space.

1.8.10 VIEW ROUTING TABLE

*D17 allows viewing the current routing table

inf

or

mation. This is view only.

1.8.12 PAKBUS NEIGHBOR FILTER

In some networks, sending beacons can be

disruptive. Enter

ing 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

ompiling 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.
