Mitsibishi Q restart automatic

[Anootje 0]

At one of our plants we have problem with Mitsibishi Q (Q26UDEH)
The PLC reset automatically by itself for unknown reason. The failure of the PLC causes a disruption in our production process.
I have make  a counter in the software for counting the first-scan system bit voor analysing.
I have exchanged the CPU, power supply, and basic rack, but the plc keeps starting up automatically.
Does anyone have suggestions for solving this problem.

The system Q cannot reset automatically This can be done via your software if enabled in the parameters.
Is it possible you can reset the power by setting an output ?
