PAC Stops Running

I have set up a dimmer channel to 3 different levels, 2 by DLT buttons and 1 by Multi Sensor.
I have created a pseudo group 200 in the PAC which is activated with any of the DLT buttons to disable the PIR when the dimmer is enabled by any of the DLT buttons.
The logic works for several cycles i.e. push one of the buttons group 200 PIR disable appears in the application log and the lights stay at the desired level when walking below the sensor.
However after a while the sensor disable appears to stop. i.e. push one of the buttons and the lights ramp to the desired level but walk below the sensor and the light level changes to match the level setpoint desired by PIR activity and the disable group 200 stops appearing in the application log.
Its as if the PAC has stopped running soon after logging off it.
Powering down and back up also allows the logic to work for several cycles but
the problem returns shortly after.
Any help appreciated, Cheers .

 

We may have some chance of helping if you post the actual logic

 

Thanks for your replies.
I didn't put the logic on as I was trying to keep the post brief.
I will check for if statements and try the diagnostic utility and post any results I see and the logic.
Cheers.

 

I haven't had chance to run the diagnostics yet but please see logic below for any ideas
I have created 2 modules.
Module 1. to disable the PIR by switching a group address 200 (kitchen PIR
disable "ON" when the kitchen lights are at 20% or 60% which are the 2 levels that can be set by the DLT.

once(Get Lighting Level("Kitchen Ceiling")=20% or
(Get Lighting Level("Kitchen Ceiling")=60% then
begin
Set Lighting State ("Kitchen PIR Disable",ON);
end;

The other switches the group address 200(kitchen PIR disable "OFF" when the kitchen lights are at 0% or 25% which is the level set by the multi sensor.

once(Get Lighting Level("Kitchen Ceiling")=0% or
(Get Lighting Level("Kitchen Ceiling")=25% then
begin
Set Lighting State ("Kitchen PIR Disable",OFF);
end;
The group address is then used in the disable setting of the multi sensor.
As I said earlier the logic seems to work fine for a short while then stops and only restarts when I log on and off or power down/up.
Hope this is clear.
Many Thanks !

 

Hello Nick.
Thanks for your reply.
I think my wording may have mislead you.
The 0% comes when the DLT times out or is turned off then the multi sensor should enable ready for the next movement.

The problem I am having is also not with the multi sensor failing to enable but the opposite i.e. enabling when it shouldn't and driving the lights to 25% when the DLT has driven them to 60% or 20%.
Cheers !

 

Does anyone have any more ideas on this one. I've checked the traffic and its quite low with the thing causing much activity is the multi sensor which sends frequent messages when activated. The problem disappears when I log on with the following sequence of events.

1:Starts with the logic not working.
2:Open Piced and check the log which includes the following messages (in order but some missed for clarity): Start Log. Log TX C Bus Yes (in red). Log RX C bus Yes (in blue). Start Power Fail recovery. End Power Fail Recovery. Logic Engine Started.
At this point the logic still doesn't work and there are no messages from C Bus.
3:Close the log. Click Options then Connect to C Bus.
4: Recheck logs which read Connect to C Bus. Time Mastering Start Up. And and various messages from C Bus including any GA's I enable via DLT buttons or PIR and the Disable PIR GA when appropriate. The logic also starts to work and the lighting works correctly for quite a while with many events happening i.e button presses, PIR movements etc.
5: I close down Piced and the logic and lights stop working correctly.

Any help appreciated.
Regards.

 

You seem to be saying that it runs fine when you have PICED running. I assume this means you also have the PAC logic running in PICED at the same time which is a bad ides as both will compete with each other. Make sure you turn off the logic in PICED if you want to test to PAC. Whenever you test logic in PICED, turn off the PAC. Rather than use the PICED logs, use the CBUS diagnostic. You can filter out just the gas you are interested in and then just let it run until it fails and see what is going on.

As an aside, you don't really need the PAC at all. Just use the logic in the output unit. I'm assuming you are using 20% and 25% just so you can tell them apart in logic rather than for the tiny light level difference. Set up the DLT as normal to control the light and make sure it works. Set up the sensor on a different ga and remove the enable ga (so it's permanently enabled). Set it's level to 20% the same as the DLT.
In the output unit, go to the logic tab and enter the sensor ga on the first line, click the channel the light is on and select MAX for dimmers or OR for relays. If the DLT is on it will control the light, if it's off the sensor will control the light.

 

Thanks a lot to you both for those ideas. I'll give them a try and let you know any results.
Cheers.

 

I think this one is resolved, Thanks for your help.
It seems the programme hadn't transferred properly.
Your comment on the logic running partly in PICED led me to the solution.
I transferred the project again and its run correctly for almost a week.
Thanks Again.
Andy.
