There are fuses for the 24vdc on the I/O boards that should be checked first.
Or if the operator panel P.B's or switches do not register on the I/O then you may have lost a 24vdc supply.

THANKS FOR THE INFO AL - THE FACT THAT THE PMCLAD SCREEN SHOWS NO I/O CHANGES IS INTERESTING - BUT I DID NOT SEE ANY FUSES ON THAT BOARD - IS THERE SPICIFIC TEST POINT TO VEIRFY THAT THE 24 VDC IS PRESENT

THANKS
