Free configuration software for your Velbus installation (Windows installer). This package also contains the drivers for the RS232 and USB interface modules. Compatible with Windows XP, Vista, 7, 8, 8.1 and 10 (desktop).
A. Caution: Velbuslink only detects changes on the bus, because the software can only process the pulses that pass through the bus.
When Velbuslink indicates that the contact is closed and you take tension off the bus, then the contacts will be open when the tension comes back on, but Velbuslink has not detected it yet, since the opening of the relay contacts has not been set on the bus.
After tension is restored, collapse and expand the relay in Velbuslink. Velbuslink then retrieves the latest status of the module, and displays it correctly.
However, most input modules set their status on the bus immediately after tension is restored. All coupled relay channels respond to this instantly. This method enables Velbus to respond instantly to sensors and such. The output modules however do not set their statuses on the bus.

Q. My program steps do not seem to work?
A. In order for your program steps to work, the respective program has to be active.
Velbus input modules can have up to three programs (program 1, 2 and 3), each of which can contain multiple program steps. At any one time, only one of the three programs (or none of them) can be active.
The active program can be set to program 1, 2, 3 or none, in the following two ways:
1. In Velbuslink, in the dialog where program steps are defined (you have to be connected to be able to do so)
2. By means of push buttons or other Velbus initiators. To do so, define a new action and select as subject the input module -> "Module programs" (see screenshot below). This will make a whole array of actions available that are related to programs, amongst others selecting the active program.
If the input modules aren't visible, activate the "inputs" filter (see image above).
If you only want to activate or deactivate the program steps of one specific push button, select as subject this push button channel.
Q. Delayed off with multiple initiators
A. The ventilation has to start when the light in the bathroom or the kitchen is switched on, and has to stop 30 minutes after the last light has been switched off. How to program this in Velbuslink? Read more ... (PDF)
Q. Light switched at 100% during the day and 25% at night
A. A light needs to be switched at full intensity during the day (07:00 - 23:00), but at night (23:00 - 07:00) at a dimvalue of 25%. How to program this in Velbuslink? Read more ... (PDF)
Q. A delay can be set on multiple locations. What are delays used for?
A. If you have defined a double action for an entry (push button), you can set the time on which the second entry will be virtually activated and not the first one.
This time can be set at 1, 2 or 3 seconds.
When using a push button for functions requiring a long press, you may want to set the time corresponding to that long press between 1 and 2 seconds.
Every dimmer will make a distinction between a short and a long press.
In some situations however, you'd rather the entry did not react immediately.
A push button with the function "everything off" is a good example. In this case, you could set the reaction time of every entry (push button) between immediate, 1, 2 and 3 seconds.This is the time the entry will wait before reacting when pushed. This way, accidentally pushing the "everything off" button will not trigger any action.
Another possible setting is never. When setting this delay, the entry (push button) will no longer work (neither will it from its programs).
Q. How can I disable and enable push buttons and sensor channels at certain times?
A. A light needs to be switched by a PIR sensor from 8:00 until 22:00, and by a push button from 22:00 until 8:00. How do I program this in Velbuslink? Read more... (PDF)
Q. How can I close a Velbus relay during a very short period (<1s)?
A. Normally in Velbus a relay cannot close for less than 1s.
To make a relay close during a very short time (<1s), the following strategy can be used:
- initiator: button; subject: relay channel; action: restartable timer, 1s
- initiator: same button; subject: a second (virtual) relay channel; action: restartable timer, 1s
- initiator: the second (virtual) relay channel; subject: the first relay channel; action: off
This will cause relay channel 1 to close and open again very rapidly.
(The button starts the two relay channels at almost the same time, after which the second relay channel almost immediately turns off the first).
