Fieldbus_Multiple Discrete Input function block status handling

Under normal conditions, a Good: Non-cascade status is passed through to OUT_Dn. The block supports a status action on failure and block error conditions.

Action on Failure

When the hardware goes bad, OUT_Dn is set to Bad status and BLOCK_ERR parameter typically indicates Other Error (depending on the device in use).
