Words 100 through 199 in the IR area of the PC are reserved for Special I/O
Units. Each Special I/O Unit is assigned ten words, of which five are needed.
These five words, used by the ID Sensor or other Special I/O Units for data
communication, are referred to as I/O refresh data (stored in the I/O refresh
data area). The five words that are not used can be used as work bits.
Note Each Unit must be assigned a different unit number. If two or more Special I/O
Units are assigned the same unit number, the system is unable to determine
which Unit is to be accessed and an I/O Unit Over error occurs, halting the
system.
