Logic Solver Discrete Input function block status handling

Under normal conditions, a GoodNonCascade status is passed through to OUT_D.

When the status becomes Bad on the input channel, FIELD_VAL_D, PV_D, and OUT_D are set to Bad status and the BLOCK_ERR parameter shows Bad PV. Status becomes Bad when line fault detection is enabled and a line fault has been detected. When SIMULATE_D is enabled, FIELD_VAL_D, PV_D, and OUT_D status are set to the simulation status held in SIMULATE_D.
