Support Questions / Re: ReadUDT "No Response from PLC. (ReadRaw)" Exception

That is the normal behavior. You need to put your code in a Try-Catch block to properly handle the exception.

Okay, thanks, I think I'll search for that

Edit:

Got it to work, thanks Archie!

Support Questions / ReadUDT "No Response from PLC. (ReadRaw)" Exception

« on: July 08, 2019, 04:36:17 PM »

I am trying to work though a couple of errors when I "loose" comms with the PLC. If I am reading a UDT and I loose communications with the PLC I get the following exception:

MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException:
'No response from PLC. (ReadRaw)'

I am on 399y28 (and I think my EthernetIpClxCom controller might be a more recent version (version 30 i think))

Any help would be appreciated, Thanks!
