Can't add new 2477D's - reason 3 - PLM going bad?

[JTsao]

I am unable to add new 2477D's to my ISY994i/PRO/Zwave.  When I attempt to do so, I get the messages in the event viewer below, but even more problematic, the PLM becomes locked up and won't communicate to anything else in my house until I unplug it, wait and plug it back in.  After resetting the PLM and the initial attempt to add the switch, the switch LEDs are blinking, so I think it received some communication.

 

I think the PLM may be going bad as it is a 2413S, several years old, V1.0, but strangely it seems to work with my already installed equipment, until I try to add the new switches in.  The greed LED seems a bit dim.  Any thoughts on this?  Any explanations why it would work but then choke upon trying to add a new switch?

 

In the listing below, I am trying to add a 2477D address 41.AA.09.

If your 2413S PLM is truly a v1.X you got your monies worth and its time to repair or replace it. If your interested in the repair process here is the on going thread with all the required parts etc.

I also suspect a V1.0 PLM is over due to fail. The dim LED is one of the signs of a failing PLM.

If you try and fix a V1.0. It has two of the capacitors {C7&C13} sticking up from the main board as the power supply needed rework.

The later revision main board was modified to put both C7 and C13 on the board.

Thanks for the replies - I am getting a new PLM to try and see if this clears up the comm issues with adding new equipment.  Right now, it's the only plausible explanation and I am seeing some of the symptoms of PLM failure.  This might also explain some erratic system behavior of late.  I have also read the repair procedure and have ordered caps to fix my V1.0 as a backup unit.  It's amazing that the PLM lasted as long as it did.  I bought this years ago with an old ISY99 that has been replaced over 2-3 years ago.

The current versions of the PLM have updated firmware and hardware. If you repair your old PLM it would be best just to keep it as a spare and use a current model.

Be sure to exactly follow the PLM replacement guidelines found here  https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu

Yes the new PLM will have a later firmware revision in it.

My 1.0 hardware PLM has a v92 firmware. My 2.1 hardware PLM has firmware v9E.

Brand new from factory may even have a later version firmware. Though I don't remember seeing a later version reported.

Got a new PLM and it fixed all problems - I think it's a V2.2.  Now that I've put it in service, I notice that everthing works better.  No more times where the motion detector should have turned on a light but did not.  Guess I should have replaced the PLM years ago.

I'd like a little better information than, "I think it's a V2.2."

[Brian H]

If you could also post the firmware version found in the PLM Info/Status tab. It could be helpful to others.

[JTsao]

I checked it's V2.2 1621 per the back of the unit and it reports a firmware version 9E.

Thank you for the information.

It may help others.
