PLM Link Table Question?

[rlanza1054]

Hi,

 

I was generating a PLM Link Table using ISY diagnostics tool.

 

It goes and does the report as it should.

 

I have able 20 Insteon device in total (maybe a little bit more), I also have a total of about 10 Scenes.

 

My question:

 

Why would the PLM that is attached to ISY have over 600 lines of lnks in its table after the report is generated?

 

Is the PLM storing ever action ever taken in that table?

 

It can be the links to the devices, even if every device is registered 3 times, it still not come to over 600 line items?

 

Thank you!

Hi Rob,

 

The reason is that for every device (button), there should be a link in the PLM otherwise:

1. ISY cannot send commands to your devices

2. You won't get status feedback from devices

 

With kind regards,
Michel

Hi,

 

I understand that the PLM has to contain the links to a device.

 

What I am not understanding, is why when I only have about 20 devices in total and only a few of these devices are linked to something, how could those 20 generate over 600 lines of links when doing the 'Show PLM Links'?

Hi Rob,

 

Links are created:

2 for each button (so if 10 of your devices are 8 button KPLS, right off the bat you will get 160 links)

1 for each node in each scene

 

With kind regards,

Based on the number of devices and scenes It sounds like Rob has some old extraneous data in his PLM. A restore PLM should clean it up.

Hi,

 

What I did before I started this thread was to actually erase by factory resetting the PLM.

 

What I have now when doing the PLM Link Table report is only 10 lines.

 

I suspect this will grow back as I end up using the devices.

 

Everything is working correctly.

 

So what is the reason again for the PLM needing to store all of the links?

 

I have not setup any local links as far as I know. Everything was setup using the ISY.

 

Question, if for example: I use the ISY to link a button on the Keypad and I set it as a crosslink. That requires me to create a scene for the button and device. When setting up that scene I set each device (device plus button on keypad) to be controller. That how I was told to do a crosslink.

 

So when I do that, is the link settings being controlled by the ISY which I am assuming it is, or was it written to the PLM, or was it written to the local devices.

 

The reason I am asking this is that I have a feeling your going to write back that by resetting the PLM to factory settings I have messed up things, even though everything is working.

 

And that if I unplug the ISY and the PLM, nothing will work, unless it was actually written locally?

You need to do a RESTORE PLM. That will populate the PLM with your data, including scenes, stored in the ISY.  NEVER do a delete PLM from the ISY.

 

When you create scenes they are stored in the PLM not the ISY. The ISY issues a scene on/off command and the PLM uses the data stored in the PLM to turn on/off the devices within a scene, this way the ISY only issues one command to the scene rather than numerous commands to all the devices. Its a much more efficient way to control numerous devices at the same time.

 

Any time you make changes to the ISY it's always good idea to do a ISY backup.

 

If you unplug both the ISY and your PLM nothing will work.  If just the PLM is plugged in then the scenes stored in the ISY will work.

I never did remove the PLM, I just manually set the PLM to factory default. Which did get rid of all those 600 links. I'm sure it was storing all the older crap (no other way to put it), when I was installing and uninstalling devices, when I removed everything from the ISY and re-installed everything.

 

I think those 600 lines had so much crap, that it was probably why I had all those issue with that micro dimmer every night.

 

I'm working great now.

 

But maybe not all the links have been written to the PLM, since I only have 1o lines now in the report.

 

I can just make a change to each scene and device to get everything into PLM.

 

If I do a restore to PLM, what I'm afraid of is putting back all the crap.

 

Is there a way to get the ISY to clean up its database, something like a 'defrag' would do, so that only current stuff it contained?

Restore PLM. Sends a software reset command to the PLM and reloads only the active links back in to it.
