AMX_NXB_MOD Module

The AMX_NXB_MOD module is provided to facilitate remote logging from NXB-KNX as well as the
"List Save" and "List Load" functions.
The AMX_NXB_MOD module is integrated with the source code as follows:
DEFINE_MODULE 'AMX_NXB_MOD' nxbMod(dvKNX)
The parameters are as follows:

AMX_KNX_Updater Module

The AMX_KNX_Updater module is optional, and is provided to support implementations (e.g. legacy
CommTec projects) that use array values for feedback control.
the NXB-KNX supports channels and levels for each actuator. The Updater module is
provided to support legacy NetLinx code (which was designed to work with the
CommTec EIB device). Moving forward the Updater module could and should be
replaced with channel and level event driven feedback from the NXB-KNX, rather
than referencing the lKNX_Value array.
The AMX_KNX_Updater module is integrated with the source code as follows:
DEFINE_MODULE 'AMX_KNX_Updater' Updater(dvKNX, lKNX_Value)
The parameters are as follows:

Accessing Actuators On the KNX Bus

To access actuators on the bus, KNX Destination Addresses must be configured on the NXB-KNX. This is
done via the KNX_Table.axi file (included). This include file maps the Destination Address, type, poll
conjunction and additional features to an actor number between 1 and 3000. Communication with the
actuators is accomplished via this actor number.

KNX_Table.axi Include File

The KNX_Table.axi file contains the definition of all actuators on the KNX bus that will be controlled or
monitored by the NetLinx system, and is integrated in to NetLinx code via the following source code line:
#INCLUDE 'KNX_Table.axi'
Refer to the Sample Program section on page 32 more add it on al information on the KNX Table and to
review sample programs that illustrate the following:

KNX_Tools.axi Include File

Additionally, the KNX_Tools.axi file should be integrated to have easy access to commonly used functions,
and is integrated in to NetLinx code via the following source code line:
#INCLUDE 'KNX_Tools.axi'
Refer to the KNX_Tools.axi section on page 37 for more information, including a listing of the functions
available in KNX_Tools.axi.

dvKNX - the physical interface for NXB-KNX, as a NetLinx D:P:S address
dvKNX - the physical interface for NXB-KNX, as a NetLinx D:P:S address
1KNX_Value - the central value array of the KNX actuators (type LONG!). No strict size is
required for the array: it should be sized appropriately for site-specific optimal performance.
The 1KNX_Value array should be defined in the DEFINE_VARIABLE section:
DEFINE_VARIABLE
...
LONG lKNX_Value[3000]
