Intelligent Building Series C-Touch Programming Reference

There are two ways of creating tags for use with a C-Touch project:

• Using the C-Bus Project Manager – see C-Bus documentation for details. In

this case the steps are to:

• Create tags (Project Manager)

• Load tags (C-Touch software)

• Use tags (in the C-Touch project)

• From the C-Touch Configuration Software – in a dialogue box that has a

drop-down list to select a group address or level, there will be two buttons

alongside which allow you to add a new tag or to edit the selected one. In

this case we:

• Create associations with Group Addresses (C-Touch software)

• Use associations (in the C-Touch project)

• Assign tag names to the Group Addresses (project manager)

If the first option is chosen then a set of tags will be ready for use in the C-

Touch configuration software. The option to load tags into a project is found in

the File | Project Details menu selection on the Project tab. To load the

desired C-Bus tags into a project select the project from the C-Bus Project drop

down box.

It is easiest to load the tags for a C-Touch project before starting. Although it is

possible to create a project using Group Addresses and subsequently assigning

tag names to the Group Addresses, this process is not recommended.

4.5 C-Bus Levels

C-Bus Group Address Levels are expressed as a number (decimal or

hexadecimal) or as a percentage (0-100%). The conversion between the level

and percent is:

Level = (Percent * 255) / 100

0% = 0

1% = 2

2% = 5

3% = 7

4% = 10

etc.

Percent = 100 * (Level + 2) / 255 keeping just the number before the decimal

point.

Eg. If level is 41, then Percent = 100*(41+2)/255 = 16.784 and we keep the 16

and hence

41=16%

Similarly,

0 = 0%

1 = 0%

2 = 1%

3 = 1%

4 = 1%

5 = 2%

etc.
