I am still evaluating this SCADA system. The connections was working fine 2 weeks ago. But since last week, I could not see live tags from RSOPC server though I could still see the PLC. While trying to solve that problem yesterday, something happened, I lost all connections. Please see the screen copy for the alarm I got from connection test. In fact, this happened many times in the last few weeks but it recovered after I reboot the PC. However this trick doesn’t work any more. Connection to MySQL is fine still.
So, please help.
