Applications
Every LONWORKS device contains an application that defines the device’s behavior. The
application defines the inputs and outputs of the device. The inputs to a device can
include information sent on L
ONWORKS channels from other devices, as well as
information from the device hardware (for example, the temperature from a temperature
sensing device). The outputs from a device can include information sent on L
ONWORKS
channels to other devices, as well as commands sent to the device hardware (for example,
a fan, light, heater, or actuator). You can use the Mini kit to write a device’s Neuron C
application.
Program IDs
Every LONWORKS application has a unique, 16 digit, hexadecimal standard program ID
with the format FM:MM:MM:CC:CC:UU:TT:NN. Table 1.3 provides a break down of
the fields within the program ID.
Table 1.3 Program ID Fields
Field Description
Format (F) A 1 hex-digit value defining the structure of the program ID.
The upper bit of the format defines the program ID as a
standard program ID (SPID) or a text program ID. The upper
bit is set for standard program IDs, so formats 8–15 (0x8–0xF)
are reserved for standard program IDs.
• Program ID format 8 is reserved for L
ONMARK certified
devices.
• Program ID format 9 is used for devices that will not be
L
ONMARK certified, or for devices that will be certified
but are still in development or have not yet completed
the certification process.
• Program ID formats 10–15 (0xA–0xF) are reserved for
future use. Text program ID formats are used by
network interfaces and legacy devices and, with the
exception of network interfaces, should not be used for
new devices.
The Mini kit can be used to create applications with program ID
format 8 or 9.
Manufacturer ID
(M)
A 5 hex-digit ID that is unique to each LONWORKS device
manufacturer. The upper bit identifies the manufacturer ID as
a standard manufacturer ID (upper bit clear) or a temporary
manufacturer ID (upper bit set).
• Standard manufacturer IDs are assigned to
manufacturers when they join L
ONMARK International,
and are also published by L
ONMARK International so
that the device manufacturer of a L
ONMARK certified
device is easily identified. Standard manufacturer IDs
are never reused or reassigned. If your company is a
L
ONMARK member, but you do not know your
