V200-18-E46B Snap-In module is firmly attached and secure.

Maybe problem with sensor configuration or connection.
Panel installed on machine or tested separately?
Is it any VFD or not suppressed contactor coil present in control box?

All the sensors are very quality and 4-20 mA. Its made from eurpe.

and snap IO is firmly very much.

And use in panel equipmant;

8 piece selenoid valve 24VDC

and

power supply with nonstop UPS.

There isn't any VFD and Contactor...

Is it flyback diode installed on solenoid cirquit?

This is most likely the source of the problem.  The screen you are seeing is what happens when an inductive pulse finds it's way back into the I/O module and kicks the PLC's watchdog timer out.  As kratmel suggests, install reverse-biased diodes across where the solenoids are connected to the I/O module.  It's probably happening when you release two or more solenoids at the same time.

Look at this post-

And here's an explanation with pictures-
