Is there any way I can understand the fields in the PSW, displayed in mainframes. Is there a way to understand what is shown in it at the time of abend and use that information to solve the abend?

You can find (hint: Google is your friend) document SA22-7871, z/Architecture Reference Summary that contains a detailed description of the PSW. However, you will find that in the vast majority of abends, having the PSW is not that helpful. The PSW is more for the use of the operating system than for a debugging programmer.
