KONNEX Configuration modes in the frame of a
modular communication stack

• Petar Tomic
• KONNEX Scientific Conference 2004

2
Why configuration ?

• One end user application may consist of one or
  more devices
• Combining of several devices to one application
  is done by configuring the devices

3
What is configuration ?

• Each devices has to know how it is linked to all
  other installed devices
• Communication addresses
• The behaviour of the device in an application is
  influenced by its settings or parameter

4
Configuration Example
5
KONNEX Configuration Modes

• Several configuration modes are defined adjusted
  to
• the type of installation environment and
• persons performing the installation

6
KONNEX Configuration Modes

• S-mode (System-mode)
• E-mode (Easy-mode)
• Controller mode
• Logical tag mode
• A-mode (Automatic-mode)

7
Applikation areas for different Configuration
Modes
8
S-mode

• Configuration with a common tool
• ETS
• Knowledge of functionality
• Provided by the installer
• Download of prepared data images
• Direct memory access
• Properties

9
S-mode
10
E-mode (controller)

• Configuration
• Without a PC
• Controller
• Defined channels in Specification
• Knowledge of functionality
• Channel information in each device
• How to link the channel in the controller

11
E-mode
12
A-mode

• Self configuration by the devices
• Functional blocks defined in Specification
• Knowledge
• Devices have the knowledge how to link to other
  functional blocks

Configuration modes in a device

• Combinations of configuration modes and real
  existing device lead to to the introduction and
  definition definitions of
• Device Profiles.

19
Device Profiles

• Definition in KONNEX Handbook (Vol. 3, Chapter
  6)
• S-mode
• BCU 1, BCU 2, BIM M112, Line coupler,
• E-mode
• Controller mode, LTE, logical tag,
• A-mode
• Application resource, Application controller

20
Profile S-mode (BCU 1)

• Resources
• Memory
• System tables (Address table, )
• Configuration mechanism
• Physical Address Assignment
• Direct memory access

21
Profile E-mode (0701)

• Resources
• Memory
• System tables (Address table, )
• Configuration mechanism
• Physical Address Assignment
• Direct memory access
• Device descriptor 2
• Link Services

22
Profile A-mode (Application resource)

• Domain Address Assignment
• Distributed Address Assignment
• Individual Address
• Functional Block Scan
• Interface Object Linking
• Group Object Linking

23
Implementation

• //------------------------------------------------
  ------------------
• // handling of device model here 0701
• //------------------------------------------------
  ------------------
• // mapping of external (EIB) addresses to
  internal ones
• // Initialize the EEPROM
• // device interface object
• // application interface object
• // Emulation of BCU 1 RAM and low ROM
• // handle memory mapped load controls
• // handle memory mapped run controls
• ......
• //------------------------------------------------
  -------------------

The Device Profile is chosen by selecting one
Device model and one configuration mode or a
combination of configuration modes.
