Re: alertGet function hangs indefinitely

Thanks Leopold,

We'll look into a work around that doesn't require the use of the alertGet() function. It seems to me that there is a bug within the alertGet() function as it should return an error, not hang indefinitely when called.

Cheers
Eric

alertGet function hangs indefinitely

Hi, We are using the alertGet function and 99.9% of the time it works as expected however on rare occasions it hangs indefinitely and never returns with an error code. We have to clear the alarm that is causing the alertGet function to hang and restart our vision to fix it and continue to process ot...

Modbus Server Smoothing

Hi, I would like to be able to apply smoothing to our Modbus Server DPEs. We are not in control of the data being written to the DPEs via the Modbus Server driver but we want to be able to smooth out noisy signals on our end. The smoothing config is unable to be added to the DPEs used in the Plant M...

Re: Vision crashes due to Oracle account logout

As v3.18 is still a supported version shouldn't the bug have also been fixed in a recent v3.18 patch?

Vision crashes due to Oracle account logout

We have recently implemented some cyber security controls on our Oracle RDB and as a result we set the IDLE_TIME to be 4 hours. However we started to get Vision crashes and we have narrowed down the cause to be this IDLE_TIME setting. To reproduce the issue we reduced the IDLE_TIME setting to 1 minu...

Modbus Exception Codes

Hi All, Does anyone know if it's possible to access the Modbus exception codes somewhere inside the internal datapoints? They don't look to be written to the _Mod_Plc DPs and are just written into the log viewer. If it is not possible to access the error codes without parsing the log viewer, does an...

Re: Unknown workstation error

We fixed the issue by updating the /etc/pam.d/wincc_oa file on both our servers. We had only updated it on the PSS1 server and overlooked the PSS2 server. The PSS2 server was recently set to active which caused the password update functionality to break as it seems the server that the UI is connecte...
