ISY issuing commands, but not receiving info from field devices

[David D]

My ISY does not appear to be receiving information from any of the field devices. It seems to transmit just fine (sunrise/sunset programs, etc.). I can issue commands from Mobilinc and the computer and they work fine, however neither Mobilinc nor the computer will display the correct status UNLESS the command is issued from Mobilinc or the computer. Anything that requires receiving feedback or commands (programs) from a wall switch or keypad does not work.

I have removed and re-applied power to the ISY and the PLM without any change in symptoms.

Is this indicative of a PLM problem, or ??? Any suggestions on how to troubleshoot further? I replaced the PLM just a few years ago (v2.1).

Have you checked the Link Database in the PLM? To see how many links are in it and if they compare to what the  system knows what it should have in it?

Some indications are low or no Links in the PLM, Works for a short time after a power cycle, LED on the side is dim or out.

If I click on "Show PLM links table", the window that pops up is empty. 

Would it hurt to try a PLM restore?

Have you checked to see if the PLM is connected?

[David D]

It’s connected. Besides physically checking the connection, I can issue commands from the ISY, but it won’t receive any.

Dumb question.  Are the devices linked to the ISY?

Can you list the device links and compare to the ISY and see if they match?

[David D]

As I stated above, the PLM table appears to be empty. 
 

BTW, are you a Simplex (Johnson Controls) fire alarm tech?

No.  I'm from Simplex Technology.

Very odd that the PLM is empty.  I'm guessing you do have devices in your Admin Console?  And they did work at some time?  Sorry haven't followed/remembered from the beginning of the thread.

Oh yeah, most of my 1900 square foot house is on Insteon. I’ve got about 30 devices, 20 programs, and a modest number of scenes. I’ve been using Insteon and ISY’s for over 10 years. I’m on my second ISY and I replaced my PLM a few years ago.

Just checking.  Can never be certain and safer to ask than to assume.  Sounds like the PLM was wiped or dying....do you see an received traffic in the event viewer in Level 3?

[David D]

Yes, I can open Mobilinc and issue a command and it shows up on the event viewer.

Any harm in doing a PLM restore?

[David D]

Well, I restored the PLM and it seems to be working again. Time will tell...

Save your nickels and dimes. You have already gone through a few. Some people just seem to have problems with them. I am using the same old unit for five years now, ?   ?with a tested spare in the junk box.

I was an X10 / Ocelot user years ago before I switched to Insteon. I just recently swapped out my first generation Insteon keypads for current versions. Maybe they'll have a more reliable PLM when I'm ready to buy another (a guy can hope, can't he?).

The latest 2413S PLM is a hardware revision 2.5. It has some improvements in the power supply area.  An updated serial port daughter board. With a new serial interface chip with a better ESD specification and a protective network on the serial I/O pins to the outside world.

Time will tell if the improvements will make the 2413S more reliable.
