Support Questions / Re: System.IndexOutOfRangeException: Index was outside the bounds of the array

« on: April 30, 2021, 06:43:37 PM »

seems to be working, i got rid of the msgbox in the catch exception and replaced it with a richtext box so i could track it.
i disconnected the plc and reconnected after if faulted.  It took longer than I expected to recover, but it finally did.  Thanks for the help, i really appreciate it.

Archie, it appears to be stable, but still breaks when I download to my plc when making changes.  Is there any way to make it self recover?

Yes, try catch.  that is the popup from the code.  I'll kill the try catch and post what happens next time it chokes.

it popped an error, but a different one this time.
this application uses a timer to read 2 arrays from the plc every 60 seconds and log the data into a csv file.
it also reads from a spreadsheet and writes recipe data to the plc.

this popped up during one of the timed array reads.  screenshot attached.

Support Questions / System.IndexOutOfRangeException: Index was outside the bounds of the array

« on: April 28, 2021, 12:14:26 PM »

Project is running.  v399x
I'm reading an array of 500 reals and an array of 500 strings.

DataCollectionValue = EthernetIPforCLXCom1.Read("DataCollectionSensors", 500)
DataCollectionName = EthernetIPforCLXCom1.Read("DataCollectionSensorsNames", 500)

No issues.

When I have to download to the plc and the comms die, I get this error:
System.IndexOutOfRangeException: Index was outside the bounds of the array
msgbox has a bunch of text from the Try/Catch, but these two are always present when this happens
EthernetIPforCLXCom.vb Lines 443/364

it never recovers unless I kill the app and restart.  What should I do to make this more robust?  Or is there any way to get the comms back without a restart?

Not sure what i'm doing wrong, I'm a PLC guy, this vb stuff is pretty new to me.
