Script Loop

[vladmci]

I installed the LM APK on a display and connected it to the LogicMachine. I have run into a major problem.
I have three DALI LED luminaires with short addresses A0, A1, and A2. The corresponding KNX switch object addresses are 1/1/1, 1/1/4, and 1/1/7.
I created a virtual KNX object 32/1/1 and attached the following event script to it:

Code:

value = event.getvalue() grp.write('1/1/1', value) grp.write('1/1/4', value) grp.write('1/1/7', value)

In the visualization, I created a standard On/Off control using 32/1/1 as both the Control and Status object.
When I operate this control, it causes complete chaos on the DALI bus. It appears that the event script is executed dozens of times instead of just once. The ON/OFF commands are continuously sent to the three DALI luminaires and they never stop. The only time the commands stop is when the DALI bus eventually seems to lock up.
Have you seen this behavior before?

You clearly have some loop there and it should not be linked to dali at all. Log the objects also the 32/1/1 and see what is triggering it. In a meantime change the grp.write to grp.checkwrite

the 32/1/1 is triggered by the visu control. But I verified the event script attached to it from the script window with "run script". In log and error log windows I have nothing. In DALI cockpit-monitor I have the "flood". Also you ca see that the command is sent two times per each iteration. I made a real "installation" for the test. The 32/1/1 group hat the scrip for several luminaries
the script is:

local value = event.getvalue()

grp.checkwrite('1/1/130', value)
grp.checkwrite('1/1/52', value)
grp.checkwrite('1/1/133', value)
grp.checkwrite('1/1/142', value)
grp.checkwrite('1/1/46', value)
grp.checkwrite('1/1/4', value)
grp.checkwrite('1/1/76', value)
grp.checkwrite('1/1/121', value)

To debug it go to object tab, select log on relevant objects. Trigger the script from visu and drop screenshot from Object logs tab.
