These read-only variables access the status of the digi-
tal inputs as an entire block. Bits 0..15 correspond to
inputs 1..16. If an I/O expansion card is present, the
IB2 and IB3 commands access inputs 17..32 and
33..48 respectively.

SWINP
This word variable represents a bit map indicating
whether or not various inputs are assigned. Bits 0..15
correspond to inputs 1..16 and reflect the assignment
(1) or non-assignment (0) of fixed inputs. Unused bits
that are not associated with fixed inputs should be
cleared.

XINP
If the STOP input is assigned, the single bit set in the
word corresponds to the input assigned to the func-
tion. A value of zero indicates that the function is not
assigned. Care must be taken to avoid assigning multi-
ple functions to the same input.
