The following bit types cannot be used when no
Expansion I/O Units are connected:
Expansion I/O Unit input bits (X)
Expansion I/O Unit output bits (Y)
Also, the bit addresses that can be used depend on
the configuration of Expansion I/O Units.
The following operations cannot be used with
versions prior to 1.10:
Setting the date (DAT1) for display with a display bit
