Fan stays on

My fan doesn't always turn off (once per month??).

This is my logic, please let me know where I went wrong:

 

The code looks OK.

What type of unit is the logic running in?

 

Looks good to me too.

About the only suggestion I can make, and it's a bit of a long shot, is that you change the last "Once" statement to an "If". If, for some unknown reason, the logic engine is detecting but not processing the first transition of Timer 3 to being greater than 600 seconds, an "If" statement will guarantee that it gets processed on a subsequent pass.

The other thing it can be is low-level comms. I know you probably think your network is working perfectly but it's worth firing up the Diagnostic Utility and running the Network Traffic Analyser to get some stats on your network. It might be there's a few errors running back there. It also might highlight something you're not expecting, e.g. lots of MMI's spread across lots of applications clagging up the bus, or difficulty communicating with a specific unit on the network.

Something else to try might be to see if, on the occasions it doesn't work, check to see if it's at a particular time that it occurs. There might be some specific moments in time where the bus gets really busy as scheduled information, or big scenes, get pushed out onto the bus and the unit running logic might be timing out as it attempts to get it's message out.

If you have another logic-capable unit on your network you can try transferring this logic module to that device. That would rule out any device-specific oddities, if there are any.

All of the above assumes the latest PICED, latest unit firmware, etc, etc.

 

Thanks for replys

Spectrum Colour.

Of course my network is perfect!!
I will check.

It's the only logic device.
Latest PICED
Latest Firmware

 

Now CBus diagnostic says (10.1.1.15 is my CNI):

 

You really need to provide more information to go along with that error message.
- Were you ever able to successfully connect to the CNI using the Diagnistic Utility?
- Are you sure that all instances of C-Gate and Toolkit/PICED/etc are closed prior to trying to connect to the CNI? The CNI can only take 1 connection at a time.
- Are you sure that your CNI is configured to use port 14000?
- Are the settings you're using in the Diagnostic Utility identical to those used by Toolkit?

 

My edit on last post was admitting my brains ability.
Changed the port to 10001 and all was good.
Just had to open my eyes and brain.
34 errors in the last 8 hours peak 2 per sec.
max 10 messages per second.

 

And....
Application: Lighting (56)
MMI Count: 10668
Average Period: 3.0 seconds
Source Unit: 42 (The Bath 1 light switch??)

 

If the logic was running in a Colour C-Touch, it would be easy to do some logging to work out what is going on.

It is possible, but probably not very likely, that the C-Touch Spectrum logic engine is resetting because of excessive logic. The easiest way to check this is to put a command in the logic Initialisation section which you will recognise in a log if you see it. For example, switch on a group you don't use for anything else.

Then connect the C-Bus Diagnostic Utility and log to a file until the fault occurs. Take note of when the fault occurred, then look in the log at that time to see if anything obvious is there.
