Measurement Application

Prerequisites: The network must have already been created in the project .

The Measurement application receives raw data in the form of voltage, current and resistance. This information is converted, scaled and then transmitted across the C-Bus to accurately represent physical measurement units such as temperature, liquid level, light level, etc. The measurement data transmitted across the C-Bus is utilized by C-Bus unit such as temperature, liquid level, light level, etc., which can process measurement application messages.

Measurement application is created using a reserved application address 228.

SpaceLogic C-Bus units which support measurement application.

General input unit
current measurement unit
5104DTSI temperature sensor
Color C-Touch Screen
PAC module
Schedule Plus +
HomeGate
eDLT key input unit
DALI Gateway
8 Channel Switchable Power Supply Dimmer
4 Channel Switchable Power Supply Dimmer
DALI-2 Gateway

The procedure to create an measurement application is similar to creating error application with a reserved address 228.

The field informations of measurement application is as explained below:

Field	Meaning
Device ID	Unique Device ID is a reference to identify a specific C-Bus unit for measurement report. The measurement Device ID drop down list allows the ability to select a value from 0- 254.
Device Name	The Device name specifies the name of the device. The drop-down list allows the selection of a unique ID between 1 - 254.
Channel ID	The Channel ID is used to specify the channel of the device from which the Measurement application data is received. The channel ID drop-down list allows the ability to select a value from 0- 255. NOTE: Channel ID starts at the next available address based on the device ID.
Channel name	The Channel name specifies the name of the channel.
Timeout Period	Time out value that is used by the Controller to monitor the object (0–2880 minutes). If no timeout value is added, it is considered as invalid with blank. If the timeout is 0, then the value are read and updated normally.
Unit Type	The Unit type displays the unit type of the value read. The below table explains the standard units that are used in measurement application.
Current Value	The Current value displays the current read value.

Standard Measurement Units

The table below contains a list of measurement units which are available to select when converting input data into measurement data for transmission across the C-Bus system.
