We have a problem with our current SCADA where sometimes it lost connection to the main PLC. One of the tech restarted the PLC and found out that it doesn't solve the problem. What's worst is all the commissioning data is GONE! Meaning all the recipe values, parameters, PID setting of the valves and the auto sequence becomes haywire. All of the data went back to April 2012 that is before the commissioning period. We are using Siemens S7 for the PLC and Intouch for the SCADA. Now everybody is in a turmoil as how to recover back the system. We called a local programmer but nothing they can do. Maybe I could get some hint on where to start or what could be the cause of the problem.
