In one of our site in India,Our ESD Input/Output card are failing after lighting.In the same network there is one more ESD Station & One DCS Controller, but this is not failing only one ESD controllers Input/Output cards are failing.
As Same UPS is supplying power to all the controllers.we had checked all the output and Input cards and are working normal the power supply unit is also working.
Can anyone suggest what might be the problem??
