Knxtopo.txt

The knxtopo.txt is a configuration file for the KNX I/O Server. The KNX Utility provides a graphical interface to modify the content of this file.

The file knxtopo.txt contains the declaration of the used datapoints of all the defined KNX I/O Servers and their functional attributes.

For each KNX datapoint we have a corresponding line with the following syntax:

<io_server_id>.<group_address> : dpt = {1 ... 18}; id = <id>; priority = {low|normal| urgent}; read={true|false}; description = <description_text>

For instance:

knx.0/0/1 : dpt = 1; id = dpt1; priority = low; read=true; description = Datapoint X

For virtual datapoints use the following syntax:

<io_server_id>.light.<id> : fb = <feedback_datapoint_address>; cmd = <command_datapoint_address>; on = {1|0}; description = <description_text>

<io_server_id>.dimmer.<id> : fb.level = <level_feedback_datapoint_address>; fb.onoff = <on_off_feedback_datapoint_address>; cmd.level = <level_command_datapoint_address>; cmd.onoff = <on_off_command_datapoint_address>; on = {1|0}; description = <description_text>

<io_server_id>.autom.<id> : fb.position = <position_feedback_datapoint_address>; fb.updown = <up_down_feedback_datapoint_address>; fb.stopup = <stop_up_feedback_datapoint_address>; fb.stopdown = <stop_down_feedback_datapoint_address>; fb.moving = <moving_feedback_datapoint_address>; cmd.updown = <up_down_command_datapoint_address>; cmd.position = <position_command_datapoint_address>; cmd.stop = <stop_command_datapoint_address>; up = {0|1}; closed = {255|0}; position = {true|false}; trip = <trip_time>; description = <description_text>

<io_server_id>.thermo.<id> : fb.setpoint = <setpoint_feedback_datapoint_address>; fb.status = <status_feedback_datapoint_address>; fb.temp = <temperature_feedback_datapoint_address>; fb.cooling.status = <cooling_status_feedback_datapoint_address>; fb.heating.status = <heating_status_feedback_datapoint_address>; fb.mode = <mode_feedback_datapoint_address>; cmd.setpoint = <setpoint_command_datapoint_address>; cmd.setpoint.mode = <setpoint_mode_command_datapoint_address>; unit = {C|F|K}; description = <description_text>

For instance:

knx.light.1 : fb = 0/1/1; cmd = 0/1/2; on = 1; description = Light 1

knx.dimmer.1 : fb.level = 0/1/23; fb.onoff = 0/1/24; cmd.level = 0/1/25; cmd.onoff = 0/1/26; on = 1; description = Dimmer 1
