User Manual

LonTalk Stack Developer’s Guide 89
allowing you to select from lists contained in a program ID definition file
distributed by L
ONMARK International. A current version of this list is included
with the LonTalk Stack.
Within the device’s program ID, you must include your manufacturer ID. If your
company is a member of L
ONMARK International, you have a permanent
Manufacturer ID assigned by L
ONMARK International. You can find those listed
within the Standard Program ID Calculator utility, or online at
www.lonmark.org/mid.
If your company is not a member of the L
ONMARK International, you can obtain a
temporary manufacturer ID from
www.lonmark.org/mid. You do not have to join
L
ONMARK International to obtain a temporary manufacturer ID.
For prototypes and example applications, you can use the F:FF:FF manufacturer
ID, but you should not release a device that uses this non-unique identifier into
production.
If you want to specify a program ID that does not follow the standard program ID
format, you must use the command-line interface for the LonTalk Interface
Developer utility. L
ONMARK International requires all interoperable LONWORKS
devices to use a standard-format program ID. Using a non-standard format for
the program ID will prevent the use of functional blocks and configuration
properties, and will prevent certification.
