Unit Numbers and I/O Word Allocation

Word allocations on Racks in Remote I/O Systems follow basically the same
pattern as the PC to which the Master is mounted, i.e., by the mounting order
of and by the number of words required for each Unit mounted for C120,
C500, C1000H, and C2000H Systems and by fixed slot words in C200H Sys-
tems.
