Compact HMI System not getting Up after Power Failure.
We have faced so many time below problem.
After Power Failure when we restar Computer System will not getin healthy. after deleting system and agin when we restore it it will run.
so what is the solution for this. because of this we loss all historical data. if any modification done during Engineering stage and this problem rise we lost all modified data.
This Problem accure in Compact HMI 5.1 and 6.0 version.
Please verify whether the SMData.dat database file is not close to 1KB.If this is the case after a power failure, then HMI service manager will not have a reference to the necessary services to be started.
I believe when the system is restored from the backup, the database file also gets restored and system gets enabled. Kindly use this as a starting point to trouble shoot.
Note: I am assuming this database file to be relevent even with Compact HMI800. The Screen shot is from an 800xA system.
