COMSub msg - Value Changes Recieved for Invalid Item Handle

I’ve started getting a lot of these messages in my console.

All coming from one particular scan class.

What’s the error indicating?

Ignition 7.5.5 - Windows 2003 32bit, Java 7
The ComSub is to a local RsLinx instance.

Sorry for the late reply. Are you still receiving this error message? If so, can you send us the entire stack trace? More information would be very useful. Thanks


No, I upgraded to 7.5.6 and rebuilt RsLinx(I was updating anyhow).

Turned out that we had a failing 1756-ENBT that was throwing Rslinx into fits.
