I have established a dialup IO device and am using IODeviceControl() function to manually connect and disconnect my IO device. I have also set the following parameter in my Citect.ini file to monitor the status of my connection in the kernel.


When I disconnect my dialup IO device, CitectSCADA crashes. What is the cause of this crash and how do I fix this?

This is a known issue in CitectSCADA 6.10 and the workaround is to remove the [Dial]Debug parameter or set the value to 0, which will stop the crash. More information will be posted when available.
