 Polisy running 5.9.1.  When using the Diagnostics->Show Device Links Table, I seem to be getting the subject error message for a large number of my Insteon devices.  The error message pops up even while the Events Viewer shows that communication commands are still being sent back and forth between the device and PLM.  In the past, I thought this type of error would show up after the Polisy had given up on polling the device.  Has anything changed?  Any suggestions on what I could try?  Most of my devices are working reliably and those with only a couple of links succeed without this error.  Any advice appreciated.

@rwsani99, could you post a copy of the event viewer for when this occurs?

There are a number of possible issues that could cause this (serious noise issues, PLM address change, PLM failure).  Need to see the event viewer to determine which path to send you down.

Thanks for the replies and I'm sorry it's taken my so long to get back with a reply.  Below is a copy of the Even Viewer when I try to Show Device Links Table and it fails.  Since my original post, I have replaced the PLM and the device does seem to respond to most commands from my Polisy. But while my overall system seems more reliable with the new PLM, I still get these failed replies when I try to Show Device Links Table.

@rwsani99,  Your log from the "show device links" is showing evidence of communication timeouts (no-response from the target device).   If things were working properly, you would see a "[INST-SRX    ] 02 50 4E.7D.16 71.17.44 XXXXX" after the [INST-ACK}. 

In the above, the PLM is re-trying communications up to 5x per request, and the ISY is re-trying 3x (15x total).  That's rather bad. 

Since you indicated that you are having issues with multiple devices, I'm am going to guess that you have a rather strong noise source near the PLM.  I say near the PLM because you are having problems with multiple devices.  I am guessing that it's a noise source, rather than a signal absorber, because it's rather intermittent.  Your second log section showed sections of total failure, followed by rather good communication (hops remaining = 2). 

Inspect the circuit where the PLM is installed for problem items (Pc's, UPS, Printers, etc).  Alternatively, you could try moving the PLM to another circuit.

Let us know how things are progressing
